Competitive Sorption of Copper and Nickel Ions from Aqueous Solution Using Peat

摘要: Bicomponent aqueous solutions of copper and nickel ions have been used to investigate the sorption metal onto peat. Peat, a low cost sorbent, has shown high capacity for single component attributed extensive carboxylic acids within its structure. Copper were selected as typical metals in effluents electroplating industries. The effects competitive batch systems studied at various ion concentrations. In this study Butler Ockrent model was modified using coefficient, η. Two models developed based on interaction coefficient first incorporates constant fixed η factor each into Butler-Ockrent equation. second variable equation; varies function sorbent surface coverage. Predicted equilibrium data are found be excellent agreement with experimental values both mole ratios sorption.
