【摘要】 文章在比较研究了几种草酸铁络合物体系对两种酞酸酯 DBP 和 DEHP 的光催化降解情况。结果表明：草酸铁络合物和草酸铁络合 物／H₂O₂体系在遮光条件下对 DBP 和 DEHP 没有降解作用。在中性 pH 值条件下，DBP 和 DEHP 在几种反应体系中的降解速率依次为：UV/草 酸铁络合物/H₂O₂＞UV/H₂O₂＞UV/草酸铁络合物＞UV＞太阳光/草酸铁络合物。UV 与草酸铁络合物对 DBP 和 DEHP 光降解的协同作用不 强，增强因子 f 分别为1． 20和1． 07。UV、草酸铁络合物与 H₂O₂的对 DBP 光降解协同作用也不明显，增强因子 f=1． 18。UV 与 H₂O₂对 DBP 光 降解存在明显的协同作用，增强因子 f：8． 78。更多还原

【Abstract】 The photedegradation of dibutyl phthalate（DBP） and di（2-ethylhexyl） phthalate（DEHP） by several ferrioxalate complexes systems was compared.The results indicated:the two phthalates were not degraded by ferrioxalate complexes and ferrioxalate complexes/H₂O₂ system in dark.The photodegradant ability of different systems are arranged as follows:UV/fernoxalate complexes/H₂O₂＞UV/H₂O₂＞UV/ferrioxalate complexes＞UV＞ sun/ferrioxalate complexes in the neutral medium。The analysis showed the synergy of UV and ferrioxalate complexes was no significant and the promoted coefficients were 1． 20 and 1． 07 for DBP and DEHP photodegradation respectively.The synergy of UV,ferrioxalate complexes and H₂O₂ was also no sig- nificant and the promoted coefficient was 1． 18 for DBP degradation.But UV and H₂O₂ displayed obvious synergetic effect and the promoted coefficient was 8． 78 for DBP degradation.更多还原
