Heterogeneous catalytic ozonation of 2-chlorophenol queous solution with alumina as a catalyst

摘要: Heterogenous catalytic ozonation of 2-chlorophenol (2-CP) in the presence γ-alumina as a solid catalyst has been investigated this research. It showed that rate for degradation TOC could increase from 21% to 43%. The pseudo-first reaction constants 2-CP 0.8688 min -1 0.1270, increasing by approximately 40%. At same time, consumption ozone was only half alone. This research also explored effects dosage, pH values and removal kinetics 2-CP. In addition, three consecutive running with revealed insignificant reduction activity. Furthermore, elimination toxicity evaluated Microtox® analysis. detoxification more stable good results.
