【摘要】 离子交换树脂上的钛用硫酸溶液洗脱后，在酸性介质中与过氧化氢发生络合显色反应，络合物的最大吸收峰位于４１０ｎｍ处。本文对影响络合显色光度法测定钛含量的因素进行了考察，建立了载钛离子交换树脂中的钛含量的测定方法，用以表征载钛离子交换树脂催化剂的催化活性，获得了满意的结果。该法是一种简便、迅速、可靠的钛含量分析方法，可用于载钛离子交换树脂酸催化剂的研究和应用。更多还原

【Abstract】 A new complex spectrophotometric method for the determination of titanium based on its complex reaction with H 2O 2 in sulfuric acid has been established The maximum absorption of complex compound is at 410nm In this paper,the effects of various factors on complex spectrophotometric determination of titanium have been studied Satisfied results can be obtained when it is used to determine the amount of titanium in ion exchange resin carrying titanium. Results also show a better correlation between the catalytic activity of ion exchange resin carrying titanium and the amount of titanium measured by complex spectrophotometric method更多还原
