Abstract:
The research uses high performance liquid chromatography to study hydrolysis behavior and hydrolysis kinetics of mixed bifunctional (VS/MCT) reactive dyes-C.I. Reactive Blue 194 in different conditions. The results show that: the two activity group (VS/MCT) of C.I. Reactive Blue 194 are hydrolyzed under alkaline condition. There are three kinds of main hydrolysis products which are hydrolyzed by VS, MCT and both; simultaneously, the process of hydrolysis is accompanied by the fracture of imino bridge. The study also confirms that the hydrolysis of C.I. Reactive Blue 194 is a pseudo first-order reaction as long. With the increase of pH value and temperature, the hydrolysis rate of dye increases.Keywords:
