新型钒氧簇-氮杂配体配合物的合成及光催化降解亚甲基蓝染料废水

Synthesis of novel vanadium oxygen cluster-aza ligands complex and photocatalytic degradation of methylene blue dye wastewater

以偏钒酸钠为原料,分别与菲啰啉、联吡啶自组装生成偏钒酸氮杂配合物,并以此物质为催化剂,光催化降解亚甲基蓝染料废水。实验结果表明,光照条件下,催化剂投加量越大,溶液pH值越小,则废水降解率越高。该类催化剂材料对有机染料废水具有良好的光催化降解作用,可作为新型的复合光催化材料。

Using sodium metavadate as raw material,the methylene blue dye wastewater was photocatalyzed by self-assembling metavadate complexes with phenolooline and bipyridine,respectively.The results show with the increase of the catalyst dosage,the decreases of the pH value of solution,the degradation rate of wastewater is higher under the light condition.These catalyst materials have good photocatalytic degradation effect on organic dye wastewater,so they can be used as new composite photocatalytic materials.
