Removal of heavy and toxic metals from wastewater using porphyrin-based covalent-organic frameworks: An emerging Field
Abstract
This mini-review assembles the current advances in the adsorption of heavy elements and toxic metals, namely Cr(VI), Mn(II), Ni(II), Cu(II), Tc(VII), Cd(II), Re(VII), Pt(IV), Au(III), Hg(II), Pb(II), and U(VI), bromate (), and iodine ( in water, as well as the visible-light-driven heterogeneous photocatalytic reduction of highly harmful metal ions into less hazardous or soluble metallic cations, mainly U(VI) + light U(IV) and Au(III) + light Au NPs, by the porous and highly colored porphyrin-based covalent-organic frameworks (COFs) in water.
