Heavy metal ions in water bodies pose a serious threat to human health and the environment. To overcome this issue, we developed polymeric quercetin–copper complex (QC) as novel adsorbent for heavy removal. This material was characterized using different techniques. Its structure also investigated density functional theory (DFT) calculations, which revealed formation of highly stable 2:1 between quercetin Cu2+ ion. The QC polymer exhibited >95% adsorption efficiency removing metals under...
