| 摘 要： | 本文依据诱导反应的基本原理,提出了一种同时测定多元素的方法;以I,~-—淀粉配合物为指示剂,用停留法研究了Ti~（3+）和Sb~（3+）诱导的Cr（Ⅵ）-I~-氧化还原反应的动力学性质,并建立了同时测定微量钛（Ⅲ）和锑（Ⅲ）的动力学—停留光度法.线性范围分别为0～2.8μg/mL Ti（Ⅲ）和0～2.0μg/mL Sb（Ⅲ）,检测限为0.016μg/mL Ti（Ⅲ）和0.010μm/mL Sb（Ⅲ）.测定了模拟样品中的钛、锑含量,结果满意.

| Abstract: | A stopped -flow inductive kinetic speetrophotometric method for simultaneous determination of multielments is proposed. The kinetics of Ti3+ and Sb3+ induced Cr( Ⅵ) -Ⅰ -redox reaction was investigated using Ⅰ3- - starch complex as indicator, and a procedure for simultaneous determination of Ti3+ and Sb3+ is proposed. Calibration graphs are linear for 0 2. 8μg/ml Ti(Ⅲ)and 0 2. 0μg/ml Sb( Ⅲ ). Ti and Sb amounts in synthetic samples are determined,and the results are satisfactory. |
