首发时间:2013-07-30
摘要:以邻苯二胺为功能单体,利用离子印迹技术制备了TMI@ POPD/TiO2/FACs。通过SEM、EDS、XRD、FT-IR、UV-vis DRS和ICP-AES等检测手段对其进行表征。在可见光下光降解抗生素废水来评价光催化活性。实验结果表明,离子印迹光催化剂对抗生素的降解效果明显好,降解率可达72.60%,并且离子印迹技术有效的固载了金属离子。

Preparation of transition metal ion imprinted photocatalysts and its photocatalytic activity
Abstract:In this paper, transition metal ions have been immobilized on TiO2/fly-ash cenospheres with poly-o-phenylenediamine. The as-prepared ion imprinting photocatalysts have been characterized by SEM, EDS, XRD, FT-IR, UV-Vis DRS and ICP-AES. The photocatalytic activity of the ion imprinting photocatalysts was studied by the degradation of antibiotics wastewater under visible light irradiation. The results show the degradation of antibiotics wastewater by ion imprinting photocatalysts is better, and it can reach 72.60%. And metal ions can be immobilized effectively by ion imprinting technology.
Keywords: environmental science transition metal ion ion imprinted photocatalysis
