• A solution containing dithionate ions is treated with bis(diethylenetriamine)nickel(II) chloride solution to precipitate dithionate as [Ni(dien)<SUB>2</SUB>]S<SUB>2</SUB>O<SUB>6</SUB> complex. After centrifugation, the concentration of nickel(II) ions in the supernatant is spectrophotometrically determined by dimethylglyoxime method. There is no interference from SO<SUB>4</SUB><SUP>2−</SUP> SO<SUB>3</SUB><SUP>2−</SUP>, S<SUB>2</SUB>O<SUB>3</SUB><SUP>2−</SUP>, S<SUB>4</SUB>O<SUB>6</SUB><SUP>2−</SUP>, HN(SO<SUB>3</SUB>)<SUB>2</SUB><SUP>2−</SUP>, S<SUP>2−</SUP>, or Fe<SUP>3+</SUP>.
