生物竹炭固定化漆酶对苯酚的吸附降解

Phenol removal using immobilized biological laccase with bamboo charcoal

摘要: 为提高漆酶的利用效率,进一步开发其在环境治理中的应用,本实验用生物竹炭固定化漆酶对苯酚进行去除。探究生物竹炭固定化漆酶、吸附降解时间、苯酚浓度、生物炭粒径、p H、固液比对苯酚的去除作用。结果表明,反应时间72 h,苯酚初始浓度为100 mg/L,生物炭粒径为10目,p H为4.5,固液比是1∶10(g/m L)时,苯酚的去除率可以达到100%。本研究结果为苯酚废水的处理提供了一种有效的方法。

Abstract: In order to improve the efficiency of laccase utilization and further develop its application of environmental governance, biological immobilization of laccase on bamboo charcoal for phenol removal was performed in this experiment. The effects of laccase immobilization, treatment time, concentration of phenol, carbon particle size, p H and solid/liquid ratio on the degradation of phenol were evaluated. The reaction time of 72 h, initial phenol concentration of 100 mg/L, biological carbon particle size of 10 mesh, p H of 4.5 and solid/liquid ratio of 1 ∶ 10 g/m L were optimal, which exhibited degradation ratio of phenol up to 100%.This study indicated an effective method for the treatment of phenol-containing pollution.
