Water quality — Determination of total arsenic — Silver diethyldithiocarbamate spectrophotometric method

Describes a procedure for water and waste water. Is applicable to concentrations in the range from 0,001 to 0,1 mg/l. In case of compounds which are difficult to decompose a procedure of digestion is described in the annex. By suitable dilution of the test portion with arsenic-free water higher concentrations may also be determined.
