摘要研究了泥炭对废水中铜、镍、锌的吸附效果。进行了间歇动力学和等温线研究，以确定接触时间、pH、吸附质初始浓度和温度对吸附的影响。实验发现，两小时的接触时间是达到吸附平衡所必需的。最佳pH值为4.5 ~ 5.0。Langmuir和Freundlich模型都很好地描述了铜、镍和锌的吸附数据。发现吸附过程是放热的。
Abstract The effectiveness of peat in adsorbing copper, nickel and zinc from wastewater was studied. Batch kinetic and isotherm studies were carried out to determine the effects of contact time, pH, initial concentration of the adsorbate, and temperature on adsorption. It was found that a contact time of two hours was necessary for the adsorption to reach equilibrium. The optimum pH was found to be between 4.5 and 5.0. The data for the adsorption of copper, nickel and zinc were described well by both the Langmuir and the Freundlich models. The adsorption process was found to be exothermic.
