Abstract

The goal of the present work was to study the sorption of humic acids (HA) from water on natural and synthetic zeolite A envisaging the drinking water treatment. Synthetic zeolite A nanoparticles were synthesized from natural clinoptilolite as Si source and sodium aluminate as Al source. In comparison with natural zeolite, synthetic zeolite A exhibited well defined pore sizes, which confer it a higher adsorption capacity. The comparative surface characterization of both natural and synthesized zeolites has been investigated by X-ray diffraction (XRD), scanning electron microscope (SEM)/ EDX analysis and FT-IR spectroscopy..
