Simultaneous adsorption of heavy metal ions (cu2+and fe2+) from binary solutions by microcrystalline cellulose (MCC): initial concentration effect, pH and kinetics studies

Abstract

In this study, simultaneous adsorption of heavy metals was examined by using binary component solutions. Microcrystalline cellulose (MCC) was used as an adsorbent for heavy metal uptake of heavy metal (Copper (Cu2+) and Ferum (Fe2+)) from aqueous solution in binary system. The result of adsorption experiment revealed that MCC presented more than 70% adsorption of Cu2+ and Fe2+ at high heavy metals solution and pH. It proposed that there are sturdy electrostatic attractions among the surface of the adsorbent and cationic heavy metal ions. Also, the kinetic studies for sorption of Cu2+ and Fe2+ onto MCC were better signified by a pseudo-second-order (PSO) model, which demonstrates chemisorption between the polymeric MCC adsorbent and heavy metal molecules. Bestowing to investigational findings, MCC is an attractive adsorbent for treatment of wastewater containing multiple heavy metal ions.
