摘要
利用痕量铂 (IV)在稀磷酸介质中对高碘酸钾氧化甲基绿褪色反应的催化作用 ,建立了测定痕量铂 (IV)的催化动力学光度法。方法检出限为 3.4× 10 - 1 0 g/mL ,线性范围为 0～ 2 4μg/L。用于催化剂及矿石中铂的测定 ,结果满意。
Based on the catalytic effect of trace platinum (IV) on oxidation of methyl green with potassium periodate in dilute phosphoric acid solution, a new kinetic Spectrophotometric method for the determination of trace platinum(IV) has been developed. The detection limit is 3.4×10+{-10} g/mL and the linear range of determination is 0～24 μg/L. The method has been applied to the determination of platinum(IV) in Pt-Re catalysts and ores samples with satisfactory results.
