Abstract
The article investigates the modified Vermiculite with chitosan and adsorption capacity of organ sorbent based on.
This paper investigates the efficiency of wastewater treatment using sorbents based on modified vermiculite and organ vermiculite. Vermiculite, a layered aluminosilicate with high cation exchange capacity and thermal stability, was chemically and thermally modified to enhance its adsorption properties. Additionally, surface modification with organic compounds was applied to obtain organ vermiculite with increased affinity for organic pollutants. The sorption capacity of both materials was evaluated for removing heavy metals (such as Pb²⁺, Cu²⁺, and Zn²⁺) and organic contaminants (such as phenols and dyes) from industrial and domestic wastewater. Experimental results demonstrated that organ vermiculite exhibited higher sorption efficiency toward organic pollutants, while thermally modified vermiculite was more effective in capturing heavy metal ions. The study confirms the potential of using natural and modified vermiculite-based sorbents as cost-effective and environmentally friendly materials for advanced wastewater treatment applications.
