摘要
以辽宁阜新含氟地下水为研究对象,采用室内静态试验方法,进行了蛇纹石吸附含氟地下水试验研究。结果表明,对于氟离子质量浓度5 mg/L的200 m L含氟地下水,在反应温度30℃,pH值为6.0,反应时间为2 h,振荡速度为150 r/min条件下,400 mg蛇纹石对氟离子吸附效果最佳,吸附容量可以达到2.326 mg/g,对氟离子去除率达到95.49%。蛇纹石对氟离子的吸附较好地符合Freundlich吸附等温模型,吸附过程符合准二级动力学模型。
Taking the fluorine-containing groundwater in Fuxin city of Liaoning province as study object,and fluorine-containing groundwater was studied by the indoor static test method.The experimental study was carried out on the adsorption of fluoride groundwater by serpentine.The results show that,the200mL fluorine-containing groundwater with fluorine concentration of5mg/L,at temperature30℃,pH value6.0,reaction time for2h,the oscillation rate was150r/min,the adsorption capacity of serpentine to fluoride ion can reach2.326mg/g and the removal rate was95.49%.The adsorption process of serpentine on F-is in good agreement with the Freundlich adsorption isotherm model and the adsorption process accords with quasi-second-order kinetics model.
