The photocatalytic degradation rules of phthalic acid esters(PAE)such as DBP(dibutyl phthalate),DCHP(dicyclohexyl phthalate) and BBP(butyl benzyl phthalate) were studied in aqueous TiO_(2) dispersions under UV irradiation.

• 在紫外光照射下；以TiO2为催化剂；研究邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二环己酯(DCHP)和邻苯二甲酸丁基苄基酯(BBP)水溶液的光催化降解规律；不同结构特征的酞酸酯在降解过程中pH值均表现为先升高；再降低的趋势.
