Evaluation Of Tea Wastes Efficiency On Removal Of Copper (Ii) And Nickel (Ii) Iones From Aqueous Solutions

Abstract
A batch system was applied to study the adsorption of Cu(II) and Ni(II) from aqueous solution using tea wastes. The effects of solution pH, tea wastes dose, initial metals concentration and contact time on the adsorption were investigated. The experimental data were analyzed using the Langmuir and Freundlich models of adsorption. Equilibrium data fitted well with the Langmuir model with maximum adsorption capacity of 125 and 111 mg g−1 for Cu(II) and Ni(II), respectively.
