摘　　要：GC(气相色谱)分析表明,溶解在水中的苯在UV(紫外光)作用下可以转化成苯酚。DO(溶解氧)和高pH对苯酚的产生有利,低pH抑制苯酚的产生。反应机理分析表明,苯既可以和DO反应,又可以和氢氧根或水反应产生苯酚。It was showed by GC that water-soluble benzene could transfer into phenol under UV illumination. The amount of phenol produced could enhance with increasing concentration of dissolved oxygen (DO) and pH, but decrease by decreasing concentration of DO and pH. The mechanism was proposed that phenol could be formed by benzene with the conditions of presenting either DO or hydroxyl or water.
