Phosphorus in the water system is an important environmental issue as it causes eutrophication and impacts water quality. Phosphorus adsorption refers to capturing phosphate ions from water and holding them onto adsorbent materials. This study is conducted to determine the efficiency of raw obtuse horn shells in phosphorus adsorption from an aqueous solution until reaching equilibrium. The rate and mechanism of phosphorus adsorption are conducted through kinetic analysis. The Langmuir isotherm and the Freundlich model are employed in the isotherm studies. The experimental data collected from the series of contact time variations and adsorbent weight measurement will be used to determine the adsorption kinetics parameters, such as the rate constants and the mechanisms of phosphorus adsorption onto the absorbent material. By creating contour plots based on the experimental data, trends and optimal operating conditions for maximizing phosphorus adsorption onto raw Obtuse Horn Shell can be identified. The result demonstrates that kinetic, isotherm, and prediction contour analysis are comprehensive for environmental management and water treatment. Also, obtuse horn shells are a cost-effective adsorbent for phosphorus removal.
