摘要
本文利用铂（Ⅳ）在稀硫酸介质中对溴酸钾氧化酸性品红反应的催化作用，建立了测定痕量铂（Ⅳ）的新型动力学光度法。方法的检出限为８．３×１０－１０ｇ／ｍｌ，线性范围为０～０．５μｇ／２５ｍｌ。应用于合成样品及含铂催化剂进行分析。
A new kinetic spectrophotometric method for the determination of trace platinum (Ⅳ) is established by use of the platinum catalysis on the oxidation reaction between acid fuchsine and potassium bromate in dilute sulphuric acid medium.The detection limit is 8.3×10 -10 g/ml and the linear range of the method is 0～0.5 mg/25 ml. The method is applied to the determination of platinum(Ⅳ) in some catalysts with a satisfactory results.
