Low-cost zeolite-based sorbents prepared from industrial perlite by-product material for Zn and Ni removal from aqueous solutions: synthesis, properties and sorption efficiency.

The conversion of waste/by-product materials into efficient sorbents is at the forefront of innovative remediation techniques. In the present study, the relationships among the synthesis conditions, physicochemical properties of synthesized sorbents and Zn and Ni removal efficiencies were studied in detail. Zeolite X, zeolite P, phillipsite, analcime, sodalite and cancrinite were synthesized from industrial perlite by-product material.
