在硫酸 ( 1 + 1 )介质中 ,Pd(Ⅱ )催化过氧化氢氧化酸性铬蓝K的褪色反应。研究了反应的最佳条件 ,建立了催化光度法测定痕量钯的新方法。方法的最低检测限为 5 97× 1 0 - 4 μg/mL。线性范围为 5 97× 1 0 - 4 ～ 2 60× 1 0 - 2 μg/mL。该法用于合成样品和含钯催化剂的分析
In sulfuric acid (1 + 1) medium, Pd (Ⅱ) catalyzes the discoloration of acidic chrome blue K by hydrogen peroxide. The optimum reaction conditions were studied and a new catalytic spectrophotometric method for the determination of trace palladium was established. The method has a limit of detection of 5 97 × 10 4 - μg / mL. The linear range was 5 97 × 10 4 - 2 60 × 10 -2 μg / mL. This method is used for the analysis of synthetic samples and palladium-containing catalysts
