In order to investigate the alkali-resistance property of reactive dyes with double kinds of active groups,taking C.I.Reactive Yellow 176for example,a series of hydrolysis test data in which the concentrations of the reactive dye varied with time,temperature and pH were determined by ion-pair reversed-phase high performance liquid chromatography(HPLC).And then relationship curves of C.I.Reactive Yellow 176hydrolysis at different conditions were obtained and pseudo-first-order kinetic model were used to eval...
