Harnessing Chitosan Beads as an Immobilization Matrix for Zero-Valent Iron Nanoparticles for the Treatment of Cr(VI)-Contaminated Laboratory Residue
The use of zerovalent iron nanoparticles (nZVI) immobilized in a chitosan (CS) polymer matrix is presented as an innovative and efficient solution for the removal of Cr(VI) in wastewater. nZVI, recognized for their high redox reactivity, have proven to be highly effective in removing various contaminants, including heavy metals. However, their tendency to agglomerate in aqueous media significantly reduces their surface area, reactivity, and mobility.
