Elevated phosphorus levels in water threaten human health and exacerbate eutrophication, leading to detrimental effects such as algae blooms and disruption of aquatic ecosystems. This study explores the potential of iron-coated hard clam shells as a cost-effective and environmentally friendly adsorbent for phosphorus removal from aqueous solutions. Leveraging the expansive surface area, high adsorption capacity, and widespread availability of hard clam shells, the investigation examines different initial concentrations (5, 10, 15, 20, 25 mg/L) and mass of adsorbents (2, 4, 6, 8, 10g). The investigation encompasses kinetic modeling, isotherm studies, and removal prediction analysis to clarify iron-coated hard clam shells' adsorption mechanisms and efficiency. The study employs pseudo-first-order and pseudo-second-order models for the kinetic model analysis. It utilizes Langmuir and Freundlich models for the isotherm model evaluation, thereby validating adsorption data through differential equation models. Applying iron-coated hard clam shells for phosphorus removal represents a noteworthy contribution as an alternative adsorbent in water treatment technologies.
