摘要

以分光光度滴定法研究了不同分子结构的阳离子型聚合物聚甲基丙烯酰氧乙基三甲基氯化铵(PTMAC)对阴离子染料甲基橙、酸性桃红3BM和酸性媒介漂兰B的脱色作用。结果表明

PTMAC的相对分子质量、离子度及阳离子基团的浓度影响脱色。它的脱色率还与出现新吸收峰的强度及其波长范围有很大关系。文中还探讨了PTMAC对阴离子染料的脱色机理。

Abstract

This paper deals with decolorization of anionic dyes

Methyl Orange

Acid Red 3BM and Mordant Blue I

by using poly(2-trimethylammoniumethyl methacrylate chloride) (PTMAC) with varying relative molecular mass and cationic ionization degree. The results show that both the relative molecular mass and cationic ionization degree of PTMAC and cationic group concentration will affect decolorization

while the decolorization rate relates to intensity and wave -length of absorption peak. Besides

the decolorization mechanism is discussed as well.
