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.
