Abstract:

The experiment used the method of SEM and IR to characterize the feature of the ZB-2 alkali anion exchange fiber before and after absorbing capsaicin so as to determine the adsorbing capability of the ion exchange fiber. Then the adsorptive speed of capsaicin on ion exchange fiber was measured，and the dominant process of film diffusion at the initial period was replaced by ion diffusion through ion exchange fiber in 3 min. Finally，the influences of stirring speed，concentration of capsaicin and temperature on ion exchange rate were investigated. For the dominant procedure of ion diffusion through ion exchange fiber，the apparent activation energy，reaction order，rate speed constant and total kinetics equation were obtained.
