三正辛胺、三异辛胺萃淋树脂对钯萃取色层分析

Study on the Extraction Chromatography of Tri-n-octylamine and Tri-iso-octylamine Levextrel Resins for Palladium

本文研究了三正辛胺（TOA）、三异辛胶（TIOA）萃淋树脂在酸性体系中对钯的静态分配比、酸度、温度和振荡时间等对吸附钯的影响。元素分析树脂的含氮量，动静态法测定树脂的饱和吸附容量，并通过等摩尔系列法及斜率法确定吸萃物的组成比，同时用红外光谱法探讨了此两种树脂的吸萃机理。

The distribution ratio (D) of tri-n-octylamine and tri-iso-octylamine levextrel resins for extraction of palladium in acid solution was studied, and the influence of acidity,temperature and adsorption time was investigated as well. The adsorption compounds of palladium from acidic solution have been identified using elemental analysis, static and dynamic saturating capaclty nlethod, constant molc method and slope method. The adsorption mceha nism has been proposed.
