中文摘要：
将杂多酸（SiW12O40^4-）负载到阴离子交换树脂上，得到SiW12O40^4-／Resin（SWR）固相光催化剂，在可见光的照射下，可以有效地活化H2O2降解染料．以罗丹明B（RhodamineB，RhB）为模型化合物，研究了不同条件下RhB的降解动力学，以及降解过程中其UV—vis光谱及体系的总有机碳（Total Organic Carbon，TOC）变化情况，结果表明RhB的共轭芳环结构被破坏，矿化率为24．2％．其它染料如孔雀绿（Malacllite Green，MG）和吖啶橙（Acridine Orange，AO）等也可以被降解和矿化．催化剂的循环实验表明SWR固相光催化剂易于分离，并且具有良好的稳定性，可以重复利用．
英文摘要：
A heterogeneous polyoxometalate photocatalyst, SiW12O40^4-/Resin （SWR）, was obtained by loading SiW12O40^4- on an anionic exchange resin and used to activate H2O2 for the efficient degradation of dyes under visible light irradiation. Rhodamine B （RhB） was employed as a model compound for the kinetic study in the photoreaction. The variations of the UV-vis spectra of RhB and the total organic carbon changes of the system indicated that the aromatic structure of RhB dye was decomposed, with a mineralization content of 24.2%. Similarly, dyes such as malachite green and acridine orange could also be degraded and mineralized. The recycle experiment suggested the excellent stability and reusability of the heterogeneous SWR photocatalyst.
