拟定了一种快速测定催化剂中铂的分析方法。该方法采用HNO3-NaCl-KMnO4-NH4 HF溶样体系,采用微波封闭溶样技术进行预处理,在pH 3.3乙酸-乙酸钠介质中,采用洗洁精为增溶、增敏试剂,以金试剂分光光度法直接进行测定。该方法的测定范围为(0.25~xx)×10-6,RSD为5.4%。
The paper designed a quick determination method of platinum in catalysts .The method adopted HNO3-NaCl-KMnO4-NH4 HF dissolution system , and pretreated samples with microwave sealed dissolution technology . Spectrophotometry is used for direct determination with cleanser essence as solubility and sensibility enhancement a -gent in media whose pH value is 3.3.The detection limit of the method is (0.25-xx) ×10 -6 ,with RSD of 5.4%.
