【摘要】 利用过氧络合物热分解法制备了锐钛矿型纳米TiO2微粉。研究了锐钛矿纳米TiO2对农药的光催化降解。结果显示对于顺反氯氰菊酯乳液以及多肼悬浮剂药物降解效果较好,但对于复杂的酸类杀菌剂则难以彻底降解。利用纳米TiO2材料对农药进行光催化降解,为防治农药对环境的污染以及消除农药残留提供了一个新途径。更多还原

【Abstract】 Anatase TiO 2 nanoparticles were prepared with th e peroxide -complex heat decomposit ion method.We investigated the photo -catalysis degradation of the agroch emicals using the anatase TiO 2 nanoparticles.Results show that th e agrochemicals such as cis -trans cypermethrin emulsion and poly -hyd razine germicides can be well degrad ed.But the pesticides with complex o rganic acid are difficult to degrade completely.The photo-cata lysis degradation of the agrochemic als using the nano-TiO 2 provides a novel method for preventi ng the environments from the agrochemical pollutions and eliminating the agro chemical remainders.更多还原
