Water pollution with heavy metals and plastic waste are major global concerns. We developed a solution addressing both: a carbon-based sorbent derived from plastic distillation, particularly plastic bottles. Analysis revealed humic acid residues. Moreover, the structure of the sorbent is enhancing surface activity and porosity for heavy metal adsorption. Unlike activated carbon, our sorbent requires no costly activation and effectively adsorbs Zn2+, Pb2+, Cu2+ ions. Optimal-temperature use yields results comparable to coal. A hybrid tower-basin system proved most efficient. Additionally, our sorbent not only does not affect the taste and odor of water, but also reduces water hardness and removes carcinogens, offering an eco-friendly, affordable approach.
