本文系统地研究了稀土与三溴偶氮胂(TBA)的动力学行为,获得经验速率方程 R=k[RE(H_2O)_m~(3+)]·[TBA]~2·[H_3O~+]~(-1).考察 RE_1-RE_2-TBA 体系后表明:双组分稀土的动力学行为是单个稀土迭加的结果,计算机的拟合图谱[A-t 和 ln(A(?)-A)-t]显示出这一特征.据此预示了可用 TBA 做速差分析的双组分稀土体系,实验结果在允许误差范围以内.本文为 RE_1-RE_2-TBA 体系的速差分析提供了有意义的经验规律.
In this paper, the kinetic behavior of rare earth and tribromoarsenazone (TBA) has been studied systematically. The empirical velocity equation R = k [RE (H 2 O) _m ~ (3 +)] · [TBA] ~ 2 · [H 3 O + ] -1 ~ (-1) .Research on the system of RE_1-RE_2-TBA showed that the kinetic behavior of the two-component rare earth was the result of single rare earth superposition. The fitted spectra of At [ -t], which indicates that the two-component rare-earth system can be used to analyze the velocity difference by TBA, and the experimental results are within the allowable error range.This paper provides meaningful meaning for the velocity difference analysis of RE_1-RE_2-TBA system The rule of thumb
