Standard Test Method for Trace Amounts of Arsenic in Inorganic Industrial Chemicals (Withdrawn 2003)
ORDER

Scope

1.1 This test method covers colorimetric determination of arsenic in inorganic industrial chemicals containing 1 to 8 [mu]g of arsenic, using silver diethyldithiocarbamate.

1.2 Annex A1 contains a method for conducting a preliminary evaluation to determine if the general method is directly applicable to the sample or if some special precaution must be observed to achieve proper accuracy and precision (see Section 5).

1.3 Annex A2 recommends a method of separating arsenic from the interference of metals or salts of metals such as chromium, cobalt, copper, etc. (see 5.1).

1.4 Annex A3 recommends a sample preparation to eliminate the interference due to nitrate (5.3).

1.5 Annex A4 recommends a sample preparation to eliminate the interference due to sulfide, in excess of trace amounts (5.3).

1.6 Annex A5 recommends a method for confirming the validity of the arsenic value if the result is suspect due to a distortion of the color of the arsenic silver diethyldithiocarbamate complex.

1.7 The values stated in SI units are to be regarded as the standard.

1.8 This standard does not purport to address all of the safety problems, 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 Note 4.
