UV/H2 O2作用下冰中苯酚的光转化及其与羟基自由基的关系
Phenol Photolysis in Ice and the Relationship between the Photolysis and Hydroxyl Radicals under UV/H2 O2 Systems
摘要
Abstract
The photolysis of phenol in a UV/H2 O2 system in ice was investigated and the effects of pH value,light intensity and the initial concentration of H2 O2 on the photolysis of phenol were discussed. In addition,Hydroxyl radicals (· OH)generated during the photolysis of phenol were trapped by dimethylsulfoxide (DMSO),thus the effect of·OH radicals on the photolysis of phenol was studied. The results show that H2 O2 significantly increased ·OH generation and enhanced the photolysis of phenol in ice.Changing light intensity,pH value and the initial concentration of H2 O2 ,the photolysis rate of phenol would increased with the increase of·OH generation.The addition of NO-2 and NO-3 inhibited the generation of·OH and the photolysis of phenol.But SO2-4 had no impact on·OH generation and the photolysis of phenol.Though CO2-3 and HCO-3 decreased ·OH generation,they also had no impact on the photolysis,which might be due to the other radicals generated in the system.关键词
