| Abstract: | The degradation of methyl orange in the presence of laccase immobilized on magnetic Fe3O4/SiO2 nanoparticles was investigated in this study.The effect of reaction parameters including initial pH of dye solution,reaction temperature,the amount of ABTS mediator and contact time as well as the reusability of immobilized laccase on the decoloration of methyl orange were studied in detail.The results showed that the activity of immobilized laccase is dependent upon reaction parameters to some degree and a high d... |
