Abstract: A natural soil rich in allophane was tested as adsorbent for the removal of phosphate ions from aqueous solution. The soil was characterized using particle size distribution, EDS, FTIR, XRD, TGA, and Nitrogen adsorption-desorption analyses. The effects of contact time, pH, initial concentration, adsorbent dose, and temperature and co-ions on adsorption were performed. The soil is Si-allophane rich as Al:Si is 1.03. It has a BET surface area of 41.7112 m²/g, total pore volume of 0.101018 cm³/g and average pore width of 96.8741 Å with over 80% particles having sizes
