Photocatalytic Efficacy of Heterocyclic Base Grafted Chitosan Magnetite Nanoparticles on Sorption of Pb(II); Application on Mining Effluent

Development of bio-based sorbents (i.e., chitosan moieties) at nanoscale size for the removal metal contaminants is main target this research. Grafting with thiazole heterocyclic derivative gives fast kinetics sorption, highly loading, and good recyclability mining leaching solution. Different analyses tools including (thermogravimetric analysis (TGA), scanning electron microscope energy dispersive spectroscopy (SEM-EDX), X-ray diffraction (XRD), Fourier transform infrared (FTIR), BET surface area (nitrogen sorption desorption), titration, TEM (transmission microscopy)) were used to investigate chemical textural properties functionalized sorbent. The was measured in normal visible light under UV emission. highest capacity pH 5, which reached 0.251 mmol Pb g?1 compared 0.346 pristine crosslinked (MCc). performances improved by functionalization; (0.7814 1.014 g?1) sorbent (MCa-ATA) UV, respectively.
