Method & Evidence

AimTo investigate the feasibility of creating an effective dye adsorbent from waste cotton fabric via graft copolymerization and subsequent functionalization.

MethodExperimental synthesis and characterization

ProcedureWaste cotton fabric was grafted with glycidyl methacrylate using a redox initiation system. The resulting copolymer was then functionalized with triethylammonium chloride to create an anion exchanger. The material's properties (surface area, thermal stability) and dye adsorption capacity were evaluated under various reaction conditions.
