TiO2对废水中硫化物的吸附性能研究
摘要:
研究了TiO2对废水中硫化物的吸附,探究了化学改性剂、时间、温度、pH及投入量对其吸附效果的影响.实验结果表明:TiO2对废水中的硫化物有一定的吸附效果,其中最佳化学改性剂为NaOH,最佳吸附时间为5h,吸附温度为40℃,溶液pH为8,投入量为80g/L.
The adsorption of sulfide in waste water by TiO2 was studied.The effects of different substances,time,solution pH and input ratio on the adsorption of sulfide from aqueous solution were investigated.The experimental results showed that TiO2 has a certain adsorption effect on sulfide in wastewater.The optimum modifier was NaOH,the optimum time was 5h,the optimum temperature was 40℃,the optimum solution pH was 8 and the optimum input ratio was 80g/L.
