Phosphate sorption on CaCO; was undertaken at different temperatures (25 -55 °C) and concentrations (1.94 - 3.23 n/mol! l). The sorption of phosphate was found to increase with the increase in both the concentration and temperature. A modified form of the Longmuir equation was used to explain the ion exchange sorption of phosphate on the CaCO;. The thermodynamic parameters also showed the favorable uptake of phosphate on the CaCO;.
