Evaluation of optimum adsorption conditions for Ni (II) and Cd (II) removal from aqueous solution by modified plantain peels (MPP)

The most ideal conditions for the adsorption of Ni (II) and Cd (II) ions onto modified plantain peel (MPP) from aqueous solution were investigated. The effects of three adsorption variables (pH, MPP dose and initial adsorbate concentration) were studied using central composite design (CCD), a sub...
