微波促进辣根过氧化物酶降解酚类废水研究
Microwave-induced accelerating of phenolic wastewater degradation with HRP
摘要
Abstract
High concentration phenol wastewater was degraded under the conditions of microwave and horseradish peroxidase (HRP) combined treatment.The catalytic degradation characteristics of reaction process were investigated by means of methods containing orthogonal experiment, double reciprocal plot and UV analysis.The experimental results show that the degradation efficiency to 60 mmol/L phenol solution is 91.2% during the optimal degradation conditions, which are 60 ℃, 5 min irradiation time and 550 W microwave power.The degradation kinetic parameter K was 0.025 63, and Km of HRP was not affected during reaction process.But other kinetics constants of vmax and Kcat were improved by 13.4%, which was the direct evidence to the synergistic effect of microwave-HRP joint technology in degradation process.It was beneficial to improve the catalytic efficiency and phenol degradation rate when HRP was used as catalyst.关键词
