| Abstract: | The degradation of azophloxine in the presence of laccase immobilized on the amino-modified magnetic Fe3O4/SiO2 nanoparticles was investigated in this study. When the concentration of azophioxine was in the 10-70mg ·L-1,the decolorization percentage of azophioxine by immobilized laccase could reach over 90% and degradation percentage could reach 70% in sequential eight cycles. In the meantime, the kinetics of decolorization reaction was generally corresponding with first order reaction kinetics models. The Km values of immobilized laccase for azophioxine was 567.27mg. L-1. |
