Abstract

Adsorption is one of the effective techniques for heavy metals removal from wastewater. Removal of cadmium ion from aqueous solutions was studied using mixture of low cost material silica gel and calcium carbonate at different mole ratio. Influence of contact time, ph, initial concentration of metal ion, dosage of solid, ratio of SiO:CaCO and particle size of adsorbent on removal percentage were investigated. Experiments were carried out at room temperature. In present study, the optimum parameters required for maximum adsorption determined as follows: Contact time=120 minutes, pH=9, initial concentration of Cd2+= 105 ppm, ratio of SiO:CaCO= 1:3 adsorbent dosage =10 gm/L.
