A new Gelatin-glutaradehyde-Poly(vinyl alcohol) bioadsorbent was synthesized by immobilizing Poly(vinyl alcohol) onto gelatin followed by cross-linking. This technique gives the bioadsorbent of gelatin good chemical resistance and mechanical strength. SEM and FT-IR were conducted for characterization of the bioadsrobent. A comprehensive adsorption study of Copper(II) removal from synthetic aqueous solution by adsorption on this bioadsorbent was conducted regarding the effects of initial pH, time, and copper(II) initial concentration. The adsorption data were applied to Freundlich isotherm equation and its contents were calculated. The results obtained showed that the new absorbent has good performance for the removal of copper(II).
