Collophanite fluorapatite particles were prepared as seed crystals with Ca2+ and F- ions, which were used to deeply purify low-concentration soluble inorganic phosphorus in water. The effects of combined reactants, reactant concentration, solution pH value and coexisting ions on the removal efficiency of phosphorus in water were investigated. To characterize the properties and clarify the mechanism of collophanite to remove soluble phosphates in water, the samples before and after pickling and phosphorus removal were characterized by scanning electron microscopy, transmission electron microscopy, thermoanalysis and Fourier transform infrared spectroscopy. Collophanite fluorapatite with calcium and fluorine exhibits the maximum phosphorus removal performance. The addition of Ca2+ ions significantly enhances the phosphorus removal efficiency, and F- ions with a low concentration have a slight effect on the phosphorus removal efficiency. Therefore, F- ions can be replaced by Ca2+ ions. When the initial concentration of phosphorus is 2 mg/L, pH value is > 6, and Ca2+ ions concentration is > 30 mg/L, the residual phosphorus concentration after the treatment is lower than 0.05 mg/L, thus meeting the Class Ⅱ standard of environmental tuality of water resource.
