| 摘 要： | 本文研究了２．４－二硝基甲苯在纯水、江水、含腐殖质纯水及合过氧化氢纯水中的光化学反应．结果表明：在影响２．４－二硝基甲苯光化学反应的因素中，过氧化氢影响最大，腐殖质次之，ｐＨ值影响最小．研究了２．４－二硝基甲苯在江水、含腐殖质纯水及合过氧化氢的纯水中光化学反应的机理．应用高压液相色谱鉴定了中间产物２．４－二硝基苯甲酸的存在．表明２．４－二硝基甲苯的光化学反应为侧链甲基光化学反应．

| Abstract: | In this paper,the photochemical reactions of 2. 4-dinitrotoluene were studied in pure water,river water,pure water containing humic substances or hychogen peroxides. The results show that hydrogen peroxide's affection for the photochemical reactions is the most,humic substance's affection is more thanph value's. The mechamsm of photochemical reactions of 2. 4 -dinitrotoluene was studied in river water,purewater containing humic substances or hydrogen peroxide. The middle product, 2. 4 -dinitrobenzoie acid,waszndentified by means of HPIC. The results show:the photochemical reactions of 2. 4-dinitroluene is the side-chain photoxdation reactions of methyl. |
