降解产物

Dichlorophenoxyacetic acid (2,4-D), a widely used herbicide, was treated by the ozonization technology in the laboratory.During the 2,4-D ozonization, the main categories of intermediates included chloric aromatics, dechlorinated aromatics and organic acids.Some of these intermediates have relatively high toxicity.Therefore, it is crucial to study the kinetics trend of intermediates diversion.

采用臭氧化高级氧化技术对2，4-D（2，4-二氯苯氧乙酸）污染物进行降解，2，4-D降解过程中会产生含氯芳香中间产物、无氯芳香中间产物和有机酸类中间产物，其中部分中间产物具有较高毒性，因此研究2，4-D臭氧化过程中间产物的动力学变化趋势是非常重要的。
