摘要
邻苯二甲酸二(2-乙基己基)酯(DEHP)是我国水环境中广泛存在的一种有机污染物,以其致畸性、致突变性、致癌性以及生殖毒性而引起广泛关注。以钛酸四丁酯为原料,四磺酸酞菁铜(CuPcTs)为敏化剂,采用水热法原位制备了CuPcTs/TiO2复合纳米光催化剂。在可见光照射下,用制备的CuPcTs/TiO2为催化剂对DEHP溶液进行了光催化降解实验,结果表明:在催化剂质量浓度为400 mg/L,pH为5,初始质量浓度为10 mg/L条件下,DEHP的降解率达到93.6%。
Di-(2-ethylhexyl) phthalate is a kind of organic pollutant widely existing in water environment in China.Di-(2-ethylhexyl) phthalate has been paid more attention due to its teratogenicity,mutagenicity and carcinogenicity.Tetrabutyl titanate is used as raw material,and copper(Ⅱ) phthalocyanine tetrasulfonate(CuPcTs) as sensitizer,the composite nano-photo-catalyst CuPcTs/TiO2 has been prepared by hydrothermal method in-situ synthesis.The degradation of di-(2-ethylhexyl) phthalate in water under visible light is studied in presence of the catalyst,CuPcTs/TiO2.The results show that when the catalyst concentration is 400 mg/L,pH=5 and the initial mass concentration=10.0 mg/L,the DEHP degradation rate reaches 93.6%.
