Description

ASTM E819 – Standard Test Method for Trace Amounts of Arsenic in Organic Industrial Chemicals (Withdrawn 2003)

1.1 This test method covers the colorimetric determination of arsenic in organic industrial chemicals with diethyldithiocarbamate. This test method is applicable to samples containing 1 ppm or more of arsenic.

Note 1-Test Method E533 describes the use of the same reagent for determining trace amounts of arsenic in inorganic chemicals. Annexes to this test method describe ways for conducting a preliminary evaluation to determine if the general method is directly applicable to a sample and for eliminating specific interferences. These should be equally helpful in the application of this test method.

Note 2-This test method is based on data described in “Food Chemicals Codex.”

1.2 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 hazards statements are given throughout this test method.
