Enhancing removal of hexavalent chromium using biochar, graphitic carbon nitride (GCN) and ZnFe-LDH from wastewater

Digest Journal of Nanomaterials and Biostructures
Here we prepared co-pyrolyzed, biochar, GCN and LDH and compared for their hexavalent chromium (Cr(VI)) adsorption capacity. Several factors such as aqueous pH, sorption contact time, metal concentration, sorbent dose and recyclability of the sorbents were investigated to assess the potential of biochar, LDH and GCN. The results showed that the maximum
