【Abstract】 The colour reaction of dihydralazine with Co²⁺ has been studied in the presence of surfactant. The composition, instability constant and molar absorptivity of the complex have been determined. The effects of interfering ion on the determination have been discussed. The method has been applied to the determination of cobalt in some drugs with satisfactory results.更多还原
