Enhancing Sodium Removal from Greywater using Modified Tripoli Adsorbents

Greywater, a byproduct of domestic activities, contains various contaminants including sodium ions which can adversely affect soil and plant health and industrial processes. This study explores the use of Tripoli, a sedimentary rock abundant in Jordan and its modified forms as potential adsorbents for sodium removal from greywater. X-ray fluorescence analysis revealed significant changes in chemical composition of Tripoli upon treatment with sulfuric acid and hydrochloric acid. Kinetic studies using the Weber and Morris intra-particle diffusion model demonstrated a high degree of agreement between experimental data and model predictions, with the rate constant (K) indicating enhanced intra-particle diffusion in samples treated at 1000°C. These findings highlight the potential of Tripoli and its modified forms as cost-effective and environmentally friendly adsorbents for sodium removal from greywater.
