摘　　要：DBP(邻苯二甲酸二丁酯)是一种难以自然降解的内分泌干扰物,广泛分布在环境中对生物和人体造成了危害。通过研究三种不同的催化剂(Fe/MCM-41,Fe/SBA-15,Fe/AC)对催化臭氧氧化法去除水中DBP效果的影响,选择出了去除效果最理想的催化剂Fe/AC,并选用Fe/AC研究了催化剂投加量不同对臭氧催化活性影响。结果表明随着催化剂投加量的增加,其吸附效果加强并逐渐掩盖了催化效果,吸附性也会逐渐达到饱和,高剂量投加催化剂不仅导致溶液浑浊,还会造成经济浪费,实际应用中并不可取。DBP （ dibutyl phthalate ） is a kind of endocrine disruptor with slow biodegradation.Due to its wide distribution and serious threats to human health, the removal of DBP has attracted more and more attention in recent year.By comparing the effects of 3 different catalysts （Fe/MCM-41, Fe/SBA-15 and Fe/AC）, Fe/AC was chosen as the best catalyst for catalytic ozonation of aqueous DBP.As dosage of Fe/AC increasing, the adsorbability of catalyst would cover its catalytic effect and become saturated.Besides causing turbid solution, a highly concentrated catalyst was not economical as well.
