本文研究了以二安替吡啉甲烷为显色剂,用吸光光度法测定锆化合物中的微量钛,考查了影响因素,确定了最佳条件,并用于合成样品的分析中取得满意的效果。 In this paper, diantipyrylmethane was used as a chromogenic reagent to determine the trace titanium in the zirconium compound by spectrophotometry. The influencing factors were investigated, the optimum conditions were determined, and the results were satisfactory for the analysis of the synthesized samples.
