ASTM D6696-10 理解氰化物类型的标准指南

This guide provides standard terminology for use in identifying and describing the different chemical forms of cyanide. The complex nature of cyanide chemistry, existence of numerous distinct chemical forms as well as the various regulatory distinctions that may be made can lead to confusion in technical discussions on cyanide and in the selection of appropriate methods for its analysis. This guide is intended to provide clarification and a common framework of terms and definitions to facilitate discussions and referencing different cyanide chemical species and groups of cyanide compounds. The use of such common terminology is particularly important from an environmental perspective because certain forms of cyanide are considered to be toxic. Therefore, their release into the environment is regulated by federal and state agencies. Thus a general understanding of cyanide chemistry and species definitions is needed for proper wastewater management and testing.1.1 This guide defines standard terminology used for the classification of the various chemical forms of cyanide. It is intended to provide a general understanding of the chemical nature of distinct cyanide species as related to chemical analysis and environmental fate and transport.

ASTM E755-08 用液体色谱法作过氧化二异丙苯化验的标准试验方法

This test method provides a means for determining the percent of dicumyl peroxide in technical and refined grades of this material. This test method is specific for dicumyl peroxide. No interference is encountered from dimethylbenzyl alcohol, acetophenone, or other minor impurities normally associated with commercial dicumyl peroxide.1.1 This test method covers the assay of dicumyl peroxide in commercially available refined grades of dicumyl peroxide. Technical grades can also be assayed, provided that impurities that interfere chromatographically are absent (see Note 1). These materials nominally contain approximately 99 and 92 % of dicumyl peroxide, respectively. Note 18212;In the assay of technical grade dicumyl peroxide, errors are possible if the product contains an impurity that elutes with the same retention time as the internal standard. A chromatogram obtained under the test conditions minus the internal standard will determine whether an interference situation exists in the assay of a particular technical grade product. If an impurity is noted, and its retention time is slightly different from that of the internal standard, the interference can often be eliminated by the use of a column known to have a high plate count. 1.2 Review the current material safety data sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. 1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 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. Specific precautionary statements are given in Section 7.
