N2 - In this study, phosphatic clay was used as a phosphate-containing material. The phosphorus was fractionated by CRM BCR-684 protocol, and inorganic phosphorus, mostly apatite phosphorus, was determined to be the major form. The elemental composition of the phosphatic clay was identified using X-ray fluorescence (XRF) spectrometry and the main compositions were CaO and P 2O5. The specific surface area, pore volume and average pore diameter were also measured. The leaching test results showed that the phosphate in the phosphatic clay was easily dissolved to aqueous phase, enabling the phosphate clay to be used as a source material for the immobilization process of heavy metals.
