Abstract: In order to develop economic value of the leaves, investigated the application prospect of the peroxidase in the Erythrina variegata's leaves in the removal of EDCs in water. The effect and best reaction conditions for the degradation of benzidine by E. variegata peroxidase-H2O2 were studied. The results showed that the E. variegata peroxidase-H2O2 had degradation effects on benzidine. Respectively, suitable reaction conditionsTemperature of 25~45 ℃, pH 7~8, H2O2/BZ=3.0~5.0(benzidine and hydrogen peroxide molar ratio), when the concentration of peroxidase was 10 U/mL, the best scavenging rate to benzidine (200 μmol/L) was 100%.

Key words: Erythrina variegata Linn., peroxidase, benzidine, degradation
