Abstract
A novel, fibrousand multifunctional group surface biosorbentwas prepared from the waste ofIrvingia gabonensis(Dika nut-DN) seed. The biosorbent potential in cheap environmentalremediation was tested using aqueous copper solution as adsorbate. Percentage Cu2+removalwasas high as 70 %. Sorption data were tested with various isotherms and kinetics models. Monolayersorption dominates the uptake of Cu2+onto DN with maximum monolayer sorption capacity of227.27 mg/g. Some level of multilayer sorption also occurred within the Cu2+-DN system thus agreater than 0.9 correlation coefficient recorded for the Freundlich sorption isotherm. PossibleCu2+uptake mechanism onto DN was proposed. Pseudo second order kinetics best described thebiosorption data while desorption results showed that Cu2+was stable on DN surface.
