Adsorption Kinetics of (+)-Catechin on Ion Exchange Fiber
Abstract:
The adsorption characteristics of (+)-Catechin on self-prepared polypropylene-based anion exchange fiber under static conditions were studied and the adsorption isotherms at different temperatures were also determined.The results show that the adsorption behavior of (+)-Catechin in dilute solution on the anion exchange fiber basically obeys in the Freundlich equation.Based on infinitesimal calculation the reaction order is 1.When the initial concentration is 44.60 mg/L,the values of the apparent rate constants at 286 K,303 K,323 K and 338 K are 0.016 7,0.039 4,0.054 5 and 0.094 4 min-1 respectively,and the rate constant values increase with the rise of temperature.
