【摘要】 研究了凹凸棒土(ATT)对罗丹明B (RhB)的吸附性能,讨论了反应温度和溶液pH值对RhB吸附过程的影响.实验结果显示,在ATT的投放量为0.800 0g、温度为313K、RhB浓度为25mg/L以及pH值为5.6的条件下,ATT吸附RhB 90min后溶液中RhB的剩余率为15.1%,说明ATT对RhB具有良好的吸附性能,且吸附过程符合Freudlich吸附模型.更多还原

【Abstract】 The adsorption properties of attapulgite(ATT)to rhodamine B(RhB)were studied,and the effects of reaction temperature and pH value on the adsorption processes were also discussed.The experimental results showed that when the amount of ATT was 0.800 0 g,RhB concentration was25 mg/L,temperature was 313 K,and pH value was controlled at 5.6,the residual rate of RhB in solution was 15.1%after adsorption for 90 min.ATT had the best adsorption performance of RhB.In addition,the adsorption process conformed to the Freudlich adsorption model.更多还原
