ICS Code (Examination of water for chemical substances): 13.060.50
scope:

This Standard specifies a silver diethyldithiocarbamate spectrophotometric method for the determination of arsenic in water and waste water. It is applicable for the determination of arsenic concentrations in the range from 0,001 to 0,1 mg/l. In the case of arsenic compounds which are difficult to decompose, a method of digestion is described in the annex, clause A1. By appropriate dillution of the test portion with arsenic-free water, higher concentrations of arsenic may also be determined. Antimony interferes with the determination Chromium, cobalt, molybdenum, nickel, mercury silver and platinum, in concentrations up to 5 mg/l, do not interfere with the determination.
