在测定钛的分光光度法中,二安替比林甲烷法的选择性好,但灵敏度低,三羟基萤光酮-表面活性剂法的灵敏度高,稳定性好,但选择性不如二安替比林甲烷,特别是钨的干扰严重。本文使用苯并吡喃类试剂作显色剂,以非离子表面活性剂Triton X-100为增溶增敏剂来测定钛,在灵敏度方面比三羟基萤光酮类要差,但选择性要优于萤光酮类。苯并吡喃类显色剂过去曾用于Ga、Ge、Ti、Tl、Mo等元素的分析,由于络合物的水溶性差,多用
In the determination of titanium spectrophotometry, diamipin methane methane selectivity, but low sensitivity, trihydroxyfluorone-surfactant method of high sensitivity, good stability, but less selective than two security for Bilin methane, especially tungsten interference serious. In this paper, the benzopyran reagent was used as the reagent, and the non-ionic surfactant Triton X-100 was used as the sensitizer to solubilize the titanium. The sensitivity was lower than that of the trihydroxyfluorone, but the selectivity Better than fluorescent ketones. Benzopyran developers have been used in the past for Ga, Ge, Ti, Tl, Mo and other elements of the analysis, due to the poor water solubility of the complex, multi-purpose
