中文摘要:

      乙二醇中的钛加入浓硫酸后，在酸性介质中与过氧化氢（H₂O₂）发生配合显色反应，配合物的最大吸收峰位于410 nm处. 对影响配合显色光度法测定钛含量的因素进行了考察，建立了乙二醇中的钛含量的测定方法,获得了满意的结果.该方法是一种简便、迅速、可靠的钛含量分析方法.

英文摘要:

      A new UV-spectrophotometric method for determination of titanium in Ethylene glycol based on its complex reaction with H₂O₂ in sulfuric acid has been established . The maximum absorption wavelength of compound is at 410 nm. In this paper, the effects of various factors on UV-spectrophotometric determination of titanium have been studied. Some better results could be obtained when it is used to determine the amount of titanium in Ethylene glycol.
