Abstract:
Industrial Wastewater, Especially From Textile Industries, Is Loaded With Harmful Contaminants Like Methylene Blue Dye And Lead (Pb²⁺) Ions, Which Can Seriously Threaten Water Quality And Aquatic Life. Traditional Treatment Methods, Such As Chemical Precipitation And Membrane Filtration, Tend To Be Costly And Often Create Secondary Pollutants. As A More Sustainable Option, Biosorption Using Affordable, Eco-friendly Adsorbents Has Gained Traction For Its Effectiveness. In Our Study, OPAC Showed Better Adsorption Efficiency Compared To CGAC, Likely Due To Its Larger Surface Area (867.5 M²/g Vs. 812.3 M²/g) And Higher Porosity. The Adsorption Process Was Driven By Electrostatic Interactions, Pore Diffusion, And Surface Complexation. These Results Underscore OPAC And CGAC As Promising, Cost-effective Adsorbents, Providing A Practical Solution For Treating Industrial Wastewater. Future Research Should Aim At Adsorbent Regeneration And Scaling Up For Better Environmental Sustainability.
