摘要

采用溶胶-凝胶法制得珍珠岩/二氧化钛(TiO₂)复合光催化材料,并对罗丹明B进行降解。考查了影响对罗丹明B降解的主要因素,包括罗丹明B溶液的初始浓度、催化剂的投放量和降解时间。研究结果表明:在罗丹明B溶液为50mL浓度50mg/L,降解时间为2.5h,珍珠岩/TiO₂用量为1.0g条件下,制得的珍珠岩/TiO₂对罗丹明B的降解率最高达到100%,对污水中的罗丹明B具有较好的降解性能。

Abstract

Perlite/TiO₂ composite photocatalytic material was prepared by sol-gel method and rhodamine B was degraded.The main factors affecting the degradation of rhodamine B were investigated,including the initial concentration of rhodamine B solution,the amount of catalyst and the degradation time.The results showed that under the condition including the concentration of rhodamine solution B was 50mL,degradation time of 2.5h and the dosage of perlite/TiO₂ was 1.0g,the highest degradation rate of perlite/TiO₂ to rhodamine B was 100%,and the degradation rate of rhodamine B in wastewater was better.
