Abstract
This review explores the use of bean pod and husk materials as natural adsorbents for water contaminants. Amid global water quality concerns and the limitations of conventional treatments, these agricultural byproducts gain recognition for their abundance, eco-friendliness, and versatile adsorption. The study found that modifying the adsorbents enhances their capacity, with K2CO3-activated bean pods showing the highest adsorption capacity at 300 mg/g for naphthalene. Isotherm and kinetic modeling, considering factors like pH and temperature, favored the Freundlich isotherm and pseudo-second-order kinetic models. The review also assessed recyclability, showing multiple uses without significant efficiency loss. Challenges and opportunities in using bean pods and husks for water purification are explored.
