摘　　要：以活性红染料废液作为研究对象,脱色率作为考察标准,探讨了TiO_2/壳聚糖/明胶复合棉织物对活性红染料废液进行吸附降解的最佳条件及重复使用效果。试验结果表明,当活性红染液初始质量浓度为20 mg/L和染液pH=3,采用试验所制复合棉织物对100 mL活性红染液室温紫外光照射180 min时,活性红染液脱色率约为100%;重复使用性较好。With reactive red dye wastewater treatment as the research object, the decolorization rate as the inspection standard, the optimum conditions of adsorption and degradation of reactive red dye wastewater by TiO2/chitosan/gelatin composite on cotton fabric and the effect of reuse were discussed. Test results showed that when reactive red dye solution initial concentration was 20 mg/L, dye solution pH=3, UV irradia- tion at room temperature for 180 rain, the decolorization of 100 mL reactive red dye wastewater was about 100%, and the reusability was good.
