In this study, powdered cockle shell was used as a bio-sorbent material for the removal of phosphates in water. The SEM-EDX, XRD and FT-IR analyses showed that calcium carbonate (CaCO3) exists in aragonite state in powdered cockle shell. The effect of pH, contact time and initial concentrations of phosphate was investigated in a series of batch-sorption experiments. Among the various factors studied, the pH was turned out to be a key variable for phosphate removal. Based on the experimental results for pH, it was found that the phosphate is chemically sorbed onto aragonite surface. At lower phosphate concentration, roughly 88% of sorption efficiency was accomplished by powdered cockle shell. The pseudo-second-order kinetic and the Langmuir isotherm models were fitted well to the sorption data of phosphate because of their higher correlation coefficients (R2).
