| 摘 要： | 研究了以ＴｉＯ２为催化剂，且将ＴｉＯ２涂布在模拟工业水处理浅池的水泥质池底表面，以直管高压汞灯为光源，对有机染料酸性玫瑰红Ｂ和晒化绿Ｂ进行光催化降解的可行性。结果表明，在实验条件下，本系统对以上染料有显著的光降解作用，浓度为２５ｍｇ／Ｌ的上述二种染料溶液，经３０ｍｉｎ光照，其降解率分别达８８．２％，此外，还探讨了染料浓度，染料体积、染料溶液ＰＨ值等因素对光降解的影响。

| Abstract: | The photocatalytic Degradation of organic dyes Acid Rose Red B and shangdacid Green B has been studied in geometries simulating shallow cement ponds.The photocatalyst was TiO 2 immobilized on cement.It showed that the dyes were remarkablely photolized under a 500w high pressure mercury lamp.The initial concentrations of 25mg/L of Acid Rose Red B and Shangdacid Green B decayed to 2.95mg/L and 3.15mg/L respectively in about 30min of irradiation.The influence of various parameters were studied. |
