摘要

以土壤中砂粒为吸附剂,研究了其对水中铜离子的吸附去除.结果表明:土壤砂粒对铜离子的吸附平衡时间为6 h;对铜离子的吸附符合Langmuir吸附理论;对铜离子吸附的最佳p H值为5;吸附过程符合准二级动力学模型;该吸附过程为自发的吸热反应.
        The adsorption and removal of copper ions by sand particles in soil were studied.The results indicated thatthe adsorption equilibrium time of copper ions by sand particles was 6 hours and the adsorption of copper ions fit the Langmuir adsorption theory quite well.The optimum pH of adsorption was obtained at 3.The adsorption process was fitted the pseudo-second order kinetic model and the process was both spontaneous and endothermic.
