Oil spills continue to pose a significant environmental issue, especially in marine ecosystems where clean-up efforts are extremely challenging and costly. Sawdust was chemically altered using sodium hydroxide, hydrogen peroxide, and hydrochloric acid in this research to increase its water-repelling and oil-attracting properties, thus enhancing its ability to absorb crude oil from seawater. The adsorption behavior was studied using the pseudo-second-order (PSO) and Elovich kinetic models at different temperatures. The PSO model achieved the highest correlation (R² = 0.9891), suggesting that chemisorption was the primary mechanism...........
