| 摘 要： | 自制了一种斜板式光反应器，将ＴｉＯ２固定在该斜板上，在铁离子存在的条件下，以太阳光为光源，对有机染料直接耐晒翠蓝ＧＬ进行了光催化降解的研究。结果表明，在实验条件下，本体系对直接耐晒翠蓝ＧＬ染料有明显的降解作用。浓度为２５ｍｇ／Ｌ的直接耐晒翠蓝染料溶液，经６０ｍｉｎ光照，其降解率达８１．４％。此外，还探讨了多种因素对光催化降解的影响

| Abstract: | A photocatalytic reactor was studied on a bench scale using sclar light as the scurce of radiation to degrade soluble dye GL(blue).The photocatalyst was titania immobilized on glass with the presence of ferric ions.It showed that GL(blue) was remarkabely photolized under the condition of the experiment.An initial concentration of 25mg/L of GL(blue) decayed to 4.65mg/L in about 60min of irradiation.The influence of parameters such as the concentration of ferric ions,initial pH of GL(blue),the slope of the plate and flow rate was studied. |
