以蒙脱石-K10（Montmorillonite K_(10)）作为Fe~(3＋)的载体制备异相Fenton催化剂（Mot-Fe）,并用此催化剂在可见光（λ＞420 nm）照射下研究其降解染料罗丹明B（Rhodamine B,RhB）和2,4-二氯苯酚（2,4-Dichlorophenol,DCP）.研究表明,选定的MotFe/H_2O_2体系能有效地降解RhB,反应300 min脱色完全,总有机碳（TOC）去除率达85.2%,反应过程中主要涉及到·OH自由基的产生和参与.可见光照射下,对DCP/MotFe/H_2O_2体系,TOC的去除率达到51.6%.催化剂具有比较好的稳定性,能够重复使用.

Fe^3＋ supported on Montmorillonite K10 as effective catalyst for heterogeneous oxidation was prepared. The catalyst was applied for the degradation of Rhodamine B （RhB） and 2, 4-Dichlorophenol （DCP） under visible irradiation （λ〉420 nm）. UV-Vis spectroscopy measurement was made to detect the photoreaction process. The results showed that RhB could be efficiently decolored by chosing RhB/ Mot-Fe/H2O2 system for 300 min irradiation, and the TOC removal rate was 85.2%. DCP mineralized rate was 51.6% at the chosen DCP/FeY/H2O2 system under ...
