摘　　要：分析了二氧化钛及β-环糊精交联聚合物对农药的降解效果,并研究了催化剂量、反应时间对实验效果的影响.实验结果表明,反应时间8 h、二氧化钛0.3 g、β-环糊精交联聚合物0.1 g的组合为最佳方案,最大去除率为98.6%.The effect of titanium dioxide and β-cyclodextrins cross-link polymer on pesticides degradation was analyzed. And the influence of catalyst quantity and reaction time was further studied. The results showed that the optimum reaction time was 8 h,TiO2 of 0. 3 g and β-cyclodextrins cross-link polymer of 0. 1 g. The maximum removal rate was 98. 6%.
