摘要：

Eco-friendly and cost-effective adsorbent material was successfully synthesized from orange peel (OP). Using H2O2, the modification of the prepared OP was carried out. SEM, XRD, EDX, TGA and FTIR analysis was conducted to characterize the modified orange peel (MOP). MOP was tested to remove (Cd2+, Co2+ and Zn2+) metal ions from wastewater. From the results, the sorption reaction kinetics follows pseudo-second-order. It also observed that the sorption process was more fitted to the Freundlich isotherm model. It was found that Q(max) values were equal to (46.25, 19.21 and 7.43) mg.g(-1) for Cd2+, Co2+ and Zn2+, respectively.
