本文研究了Ga(Ⅲ)与TAPC的显色反应,确定络合物组成为Ga(Ⅲ):TAPC=1:2,表观摩尔吸光系数为6.75×10~4L/(mol·cm)提出了一个简便、灵敏测定微量镓的分析方法,并用于改性 HZSM-5催化剂中镓的测定,获得满意的结果。
In this paper, the color reaction of Ga (Ⅲ) with TAPC was studied. The composition of Ga (Ⅲ): TAPC = 1: 2 and the apparent molar absorptivity of 6.75 × 10 ~ 4L / (mol · cm) A simple and sensitive method for the determination of trace gallium was developed and used for the determination of gallium in the modified HZSM-5 catalyst to obtain satisfactory results.
