摘　　要：本文发现了钌 ( )对 KIO4氧化二安替比林苯基甲烷 ( DAPM)的增色反应有显著的催化作用 ,由此建立了测定痕量钌的催化分光光度分析法 ,并且测定了一些动力学参数。方法的线性范围为 2 .0 -1 4.0 μg/L,检出限为 2 .0× 1 0 - 9g/m L,用于岩矿中痕量钌的测定 ,其结果令人满意。The catalytic action of Ru(Ⅲ) on the oxidative color reaction of diantipyrylphenylmethane (DAPM) with potassium periodate in phosphoric acid medium at 90℃ water bath was found.A new catylytic spectrophotometric method for the determination of Ru(Ⅲ) was established.Some kinetic parameters were also studied.The linear range of the method is 2.0- 14.0μg/L .The detection limit is 2.0×10 -9 g/mL.This method has been applied to the determination of Ru(Ⅲ) in ores with satisfactory results.
