ASTM D5085-02 用化学抑制离子色谱法测定大气湿沉积物中氯化物、硝酸盐、硫酸盐含量的标准试验方法

This test method is useful for the determination of the anions: chloride, nitrate, and sulfate in atmospheric wet deposition. Fig. X1.1 in the appendix represents cumulative frequency percentile concentration plots of chloride, nitrate, and sulfate obtained from analyses of over 5000 wet deposition samples. These data may be used as an aid in the selection of appropriate calibration solutions. (3)1.1 This test method is applicable to the determination of chloride, nitrate, and sulfate in atmospheric wet deposition (rain, snow, sleet, and hail) by chemically suppressed ion chromatography (1). For additional applications refer to Test Method D 4327.1.2 The concentration ranges for this test method are listed below. The range tested was confirmed using the interlaboratory collaborative test (see Table 1 for statistical summary of the collaborative test).MDL (mg/L) (2)Range of Method (mg/L)RangeTested (mg/L)Chloride0.030.09-2.00.15-1.36 Nitrate0.03 0.09-5.0 0.15-4.92 Sulfate 0.03 0.09-8.0 0.15-6.521.3 The method detection limit (MDL) is based on single operator precision (2) and may be higher or lower for other operators and laboratories. The precision and bias data presented are insufficient to justify use at this low level, however, many workers have found that this test method is reliable at lower levels than those that were tested.1.4 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.

Standard Test Method for Determination of Chloride, Nitrate, and Sulfate in Atmospheric Wet Deposition by Chemically Suppressed Ion Chromatography

ASTM D5086-01 用火焰原子吸收分光光度法测定大气作用下湿沉积物中钙、镁、钾和钠含量的标准试验方法

This test method may be used for the determination of calcium, magnesium, potassium, and sodium in atmospheric wet deposition samples. Emphasis is placed on the easily contaminated quality of atmospheric wet deposition samples due to the low concentration levels of dissolved metals commonly present. Annex A1 represents cumulative frequency percentile concentration plots of calcium, magnesium, potassium, and sodium obtained from analyses of over five thousand wet deposition samples. These data may be used as an aid in the selection of appropriate calibration standard concentrations. (3)1.1 This test method is applicable to the determination of calcium, magnesium, potassium, and sodium in atmospheric wet deposition (rain, snow, sleet, and hail) by flame atomic absorption spectrophotometry (FAAS).
