Abstract
A novel, fibrous and multifunctional group surface biosorbent was prepared from the waste of Irvingia gabonensis (Dika nut-DN) seed. The biosorbent potential in cheap environmental remediation was tested using aqueous copper solution as adsorbate. Percentage Cu2+ removal was as high as 70 %. Sorption data were tested with various isotherms and kinetics models. Monolayer sorption dominates the uptake of Cu2+ onto DN with maximum monolayer sorption capacity of 227.27 mg/g. Some level of multilayer sorption also occurred within the Cu2+-DN system thus a greater than 0.9 correlation coefficient recorded for the Freundlich sorption isotherm. Possible Cu2+ uptake mechanism onto DN was proposed. Pseudo second order kinetics best described the biosorption data while desorption results showed that Cu2+ was stable on DN surface.
