Abstract
Anthropogenic activities have resulted in considerable water quality degradation in water sources due to a common problem of the excessive nutrient content (phosphorus) in receiving water, resulting in eutrophication. Even though various wastewater treatment methods have been applied, focusing on phosphorus removal through biological, physical, and chemical treatment, there is still a need to identify the eco-friendly method using the adsorption process and verify the theoretical and experimental data via kinetic and isotherm models. Hence, this study investigates phosphorus removal efficiency from water onto raw marsh clam shells and verifi es the experimental and theoretical data with kinetic and isotherm studies. The variable of this study used different masses (2, 4, 6, 8, 10 g) of adsorbents with particle sizes from 1.18 mm to 2.36 mm to remove phosphorus from an aqueous solution (5 mg/L). The physicalchemical properties of adsorbents were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray Fluorescence (EDXRF), and Fourier Transform Infrared Spectroscopy (FTIR) to support the experimental data and identify the possibility of phosphorus adsorption. The batch experiment data obtained were verifi ed using the kinetic (pseudo-first-order and pseudo-second-order) and isotherm (Langmuir and Freundlich) models. The experiments showed that the best contact time for all masses was 1440 min and the best adsorbent dose was 10 g with 78.0%removal. By comparing the two adsorption isotherm models, the study finds that the adsorption isotherm fits the Langmuir isotherm model with a correlation coefficient, R 2 of 0.9006. The novel use of adsorbent marsh clam shell as a potential adsorbent in the application of future water treatment technologies.
