Abstract


  

The present study investigates the synthesis of cellulose phosphate (CP) from corn hulks as an adsorption material for the removal of two heavy metals, lead and cadmium, from synthesis wastewater. The CP was synthesized by the cellulose extraction from corn husks and following the phosphorylation reaction. Then, the heavy metals adsorption ability of cellulose phosphate were tested. The results reveal that yield of cellulose was 21.13 percent by weight and synthesis of CP found that yield of phosphate was 0.415 percent by weight. The efficiencies of CP for removal different heavy metals from synthesis wastewater were tested. The heavy metals adsorption ability was observed that the efficiency of CP for adsorption of lead is higher than efficiency for adsorption of cadmium.      In addition, the efficiency of adsorption also depend on the incubation time and amount of CP.        

Keywords : cellulose  phosphate, corn husks, heavy metals absorption
