Column performance in lead removal from aqueous solutions by fixed bed of natural zeolite–clinoptilolite
چکیده انگلیسی

The aim of this investigation is removal of lead ions from aqueous solutions using the column method with more successive service and regeneration cycles. The experiments were performed at constant temperature and dimensions of column and fixed bed of zeolite, with variation of zeolite particle sizes and flows through the bed, concentrations of lead solutions and the regenerate. Eight service and regeneration cycles were performed without changes of the breakthrough and exhaustion capacity. The highest effectiveness of the column performance has been attained for the zeolite particle size of 0.6–0.8 mm, at the initial concentration of 212.5 mg Pb/L and the flow rate of 2 mL/min. At these experimental conditions, the optimal values of the empty bed contact time and high of the mass transfer zone have been achieved.
