摘要
建立了用分光光度法测定CO助燃剂中铂含量的方法．在盐酸介质中，Pt（Ⅳ）被氯化亚锡溶液还原，生成黄色的亚氯铂酸（H2PtCl4），最大吸收波长位于403nm处．方法简单、快捷、准确，回收率在97％～103％之间，相对标准偏差小于2．0％．在优化的实验条件下，助燃剂中的常见元素对测定铂含量无干扰．
A method for the determination of platinum content in CO combustion improver using a spectrophotomeic method is described. In an HC1 medium, Pt（ Ⅳ ）was reduced by SnCI2 solution and formed a yellow color chloroplatious acid（ H2PtCI4 ）. The absorption maxima of which is at a wavelength of 403 nm. The method features simplicity,rapidness and accuracy, with a recovery in the range of 97% to 103% ,and the relative standard deviations were less than 2%. The common elements existed in the CO combustion improver do not interfere the determination of platinum under the optimized test conditions.
