| Abstract: | The degradation of trace benzene in water was studied by using 185 nm UV light and oxidation technique.The influence of concentration of benzene,degradation time,pH value of solution,and oxidants on the degradation of benzene was investigated.The degradation products were analyzed by using GC/MS method and the degradation mechanism was presented.The results showed that the trace benzene was effectively degradated by 185 nm UV light and oxidation technique,and after treating for 3 min,the degradation efficie... |
