Summary This standard specifies the methods for determining arsenic content in bismuth concentrate by DDTC-Ag spectrophotometry and ammonium ferrous sulfate titration. This standard is applicable to the determination of arsenic content in bismuth concentrate, with a determination range (mass fraction) of 0.010% to 1.00% for DDTC-Ag spectrophotometry and a determination range (mass fraction) of 1.00% to 10.00% for ammonium ferrous sulfate titration.
