摘要：
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.
