本文研究了BTAPC与 Ga(Ⅲ)的显色反应条件,确定络合物组成为1:3,表观摩尔吸光系数为1.22×10~5I.mol~(-1)·cm~(-1)。提出一个简便、灵敏的测定微量镓的分析方法,并用于催化剂中镓的测定,获得满意的结果。
In this paper, the color reaction conditions of BTAPC and Ga (Ⅲ) were studied. The composition of the complex was determined to be 1: 3 and the apparent molar absorptivity was 1.22 × 10 ~ 5I.mol -1 cm -1. . A simple and sensitive method for the determination of trace gallium was proposed and used for the determination of gallium in the catalyst to obtain satisfactory results.
