Sažetak
The removal of lead ions from aqueous solutions by the column method using the fixed bed of natural zeolite clinoptilolite has been examined. 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.
