ASTM D3697-17 水中锑含量的标准试验方法

5.1 Because of the association with lead and arsenic in industry, it is often difficult to assess the toxicity of antimony and its compounds. In humans, complaints referable to the nervous system have been reported. In assessing human cases, however, the possibility of lead or arsenic poisoning must always be borne in mind. Locally, antimony compounds are irritating to the skin and mucous membranes. 5.2 ICP-MS may also be appropriate but at a higher instrument cost. See Test Method D5673. 1.1 This test method covers the determination of dissolved and total recoverable antimony in water by atomic absorption spectroscopy.2 1.2 This test method is applicable in the range from 1 to 15 μg/L of antimony. The range may be extended by less scale expansion or by dilution of the sample. 1.3 The precision and bias data were obtained on reagent water, tap water, salt water, and two untreated wastewaters. The information on precision and bias may not apply to other waters. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Antimony in Water

ASTM D7678-17 用中红外激光光谱学和溶剂萃取法测定水和废水中总油脂(TOG)和总石油烃(TPH)的标准试验方法

5.1 The presence and concentration of total oil and grease as well as total petroleum hydrocoarbons, in domestic and industrial wastewater is of concern to the public because of its deleterious aesthetic effect and its impact on aquatic life. 5.2 Regulations and standards have been established that require monitoring of total oil and grease as well as total petroleum hydrocarbons in water and wastewater. 1.1 This test method covers the determination of total oil and grease (TOG) and total petroleum hydrocarbons (TPH) in water and waste water that are extractable by this test method from an acidified sample with a cyclic aliphatic hydrocarbon (for example cyclohexane, cyclopentane) and measured by IR absorption in the region from 1370 cm-1 to 1380 cm-1 (7.25 μm to 7.30 μm) using a mid-IR laser spectrometer. Polar substances are removed by clean-up with Florisil.2 1.2 This test method also considers the volatile fraction of petroleum hydrocarbons, which is lost by gravimetric methods that require solvent evaporation prior to weighing, as well as by solvent-less IR methods that require drying of the employed solid phase material prior to measurement. Similarly, a more complete fraction of extracted petroleum hydrocarbons are accessible by this test method as compared to GC methods that use a time window for quantification, as petroleum hydrocarbons eluting outside these windows are quantified too. 1.3 This test method covers the range of 0.1 mg/L to 1000 mg/L and may be extended to a lower or higher level by extraction of a larger or smaller sample volume collected separately. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5627-17 颗粒状离子交换树脂的水可萃取残留物的标准试验方法

5.1 The presence of water extractables in ion-exchange resins can cause fouling of other materials downstream and contamination of process water. The quantity of water extractables is sometimes used as a specification to indicate resin quality, and typical values are 0.01 to 0.18201;%. 5.2 It is recognized that this test method may not remove all potential sloughage products and does not measure volatile compounds. More extensive extraction and identification of compounds may be needed in specific cases. 1.1 This test method covers the measurement of water soluble extractable residue from particulate ion-exchange resins based on elevated temperature extraction and gravimetric determination of residue. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Water Extractable Residue from Particulate Ion-Exchange Resins

ASTM D1291-17 评估水中氯需求量的标准实施规程

5.1 Chlorine is added to potable water, waste water, and industrial water for a variety of purposes. Some of these purposes are: 5.1.1 To eliminate or reduce the growth of microorganisms in water, 5.1.2 To destroy or modify decomposable organic substances so as to reduce the biochemical oxygen demand of the water, 5.1.3 To eliminate or reduce taste, odors, and color in the water, 5.1.4 To separate grease in waste water by eliminating the protective colloidal effect of proteins present, and 5.1.5 To destroy or modify substances in the waste water that react directly by oxidation, such as ammonia, cyanates, cyanides, ferrous iron, nitrites, phenol, phosphorus, sulfides, sulfites, thiocyanates, and other oxidizable constituents. 5.2 It is important to avoid over-chlorination in order to minimize chemical consumption, meet restrictions specified by regulatory agencies, and minimize equipment degradation. 1.1 This practice provides a means of estimating the quantity of chlorine required to be added to a unit volume of water to accomplish a predetermined treatment objective or to completely react with all chlorine reactable substances in the water, or both. 1.2 Temperature, pH, and initial chlorine dosage are all variables in estimating the optimum chlorination practice. The effects of these variables can be evaluated using this practice. 1.3 Chlorine residual is determined using Test Method D1253. 1.4 This practice is applicable to all types of water in which the stated treatment objective can be evaluated or residual chlorine can be measured, or both. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 7.5.1.

Standard Practice for Estimation of Chlorine Demand of Water

ASTM D5257-17 用离子色谱法测定水中可溶六价铬的标准试验方法

5.1 Hexavalent chromium salts are used extensively in the metal finishing and plating industries, in the leather industry as a tanning agent, and in the manufacture of paints, dyes, explosives, and ceramics. Trivalent chromium salts are used as mordants in textile dying, in the ceramic and glass industry, and in photography. Chromium, in either oxidation state, may be present in wastewater from these industries and may also be discharged from chromate-treated cooling waters. 5.2 Hexavalent chromium is toxic to humans, animals, and aquatic life. It can produce lung tumors when inhaled and readily induces skin sensitization. It is not known whether cancer will result from ingestion of chromium in any of its valence states. 5.3 Ion chromatography provides a means of separating the hexavalent chromium from other species present in the sample, many of which interfere with other detection methods. The combination of this separation with a sensitive colorimetric detection method provides a selective and sensitive analytical method for hexavalent chromium with minimal sample preparation. 1.1 This test method covers procedures for the determination of dissolved hexavalent chromium in wastewater, surface water, and drinking water. 1.2 The precision and bias of this test method has been tested in reagent water and industrial wastewater and has been found suitable over the range of approximately 1 to 1000 μg/L. Higher levels can be determined by appropriate dilution. 1.3 Samples containing very high levels of anionic species (that is, chloride, sulfate, etc.) may cause column overload. Samples containing high levels of reducing species (that is, sulfides, sulfites, etc.) may cause reduction of Cr(VI) to Cr(III). This can be minimized by buffering the sample to a pH of 9 to 9.5, filtering it, storing it at <6°C. A holding time of 28 days may be used if the user can demonstrate that such holding time does not affect sample integrity in accordance with U.S. EPA 40 CFR 136, Part II. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
