Renewable P-type zeolite for superior absorption of heavy metals: Isotherms, kinetics, and mechanism

This study developed a novel P-type zeolite capable of efficiently removing heavy metals, particularly lead (Pb²⁺), from aqueous solutions. The zeolite demonstrated impressive adsorption capacities, with Pb²⁺ removal rates reaching 97% after five regeneration cycles. The process was rapid, with Pb²⁺ levels dropping from 7.5 ppm to 0.6 ppb within
