【摘要】 制备了硅钨酸改性凹凸棒土,其结构通过XRD表征。探讨了改性凹凸棒土对含酚废水的去除效果,并确定了苯酚初始浓度、溶液pH、投加量和吸附时间对吸附性能的影响。实验结果表明,当苯酚溶液的初始质量浓度为100 mg/L、pH=9、改性凹凸棒土投加质量浓度为10 g/L、吸附时间为60 min时,苯酚的去除率达到77.75%。更多还原

【Abstract】 Modified attapulgite has been prepared,and its structure is characterized by XRD.The removing effect of modified attapulgite on the treatment of phenol-containing wastewater is discussed.The influences of the initial concentration of phenol,pH of the solution,dosage of modified attapultite and adsorption time on the adsorption capacity are decided.The experimental results show that the phenol removing rate reaches 77.75%,when the initial phenol concentration is 100 mg/L,pH of the solution is 9,dosage of modified attapulgite is 10 g/L and adsorption time is 60 min.更多还原
