摘要
采用水热反应制备碳微球,通过溶胶凝胶法在其表面水解缩合生成SiO_(2)/C核壳结构,在核壳架构表面负载硝酸铜及硝酸锌,以酸性大红染料废水为目标物,通过对酸性大红染料废水的降解率对催化剂进行性能评价.实验结果表明:在浸渍液硝酸铜质量分数为15%时,催化剂可促进臭氧较大程度产生·OH等强氧化性活性物质,对酸性大红染料废水的去除率可以达到99%以上.
Carbon microspheres were prepared by hydrothermal reaction,the core-shell structure of SiO_(2)/C was formed by hydrolyzing condensation on the surface by sol-gel method.The copper nitrate and zinc nitrate were used to degrade the acid red dye wastewater.The performance of the catalyst was evaluated by the degradation rate of acid scarlet dye wastater.When the immersion solution contains 15%copper nitrate,ozone is catalyzed by catalyst to produce•OH and other active substances with strong oxidation.The removal rate of acid red dye wastewater was increased to 99%.
