BiOCl/桔子皮生物炭复合催化剂光催化降解环丙沙星

Photocatalytic Degradation of Ciprofloxacin with BiOCl/Orange Peel Biochar Composite Catalyst

本文以桔子皮生物炭为载体,通过简单的溶剂热法合成了新型的BiOCl/C复合材料,并以环丙沙星为目标污染物,评估了复合材料的光催化活性。研究结果表明,受益于生物炭与BiOCl之间的协同作用,BiOCl/C催化剂表现出比单一BiOCl更为优异的光催化性能。在环丙沙星浓度为20mg·L^(-1),溶液pH为7.0,光照时间60min的条件下,BiOCl/C催化剂对环丙沙星的降解效率可达98.1%。重复使用实验结果表明,该催化剂拥有优异的可重复使用能力。本研究结果可为环丙沙星废水的治理提供一种性能优异的催化剂。

In this study,a novel BiOCl/C composite material was synthesized by simple solvothermal method applied orange peel biochar as carrier,and its photocatalytic activity was evaluated by using ciprofloxacin as target pollutant.The results showed that BiOCl/C catalyst exhibited better photocatalytic performance than pure BiOCl due to the synergistic effect between biochar and BiOCl.Under the conditions of ciprofloxacin concentration of 20mg/L,solution pH was 7.0 and light illumination was 60min,the degradation efficiency of ciprofloxacin by BiOCl/C catalyst reached 98.1%.In addition,the reuse experiments showed that the catalyst had excellent reusable ability.The results could provide a catalyst with excellent performance for the treatment of ciprofloxacin wastewater.
