Research Progress of Adsorption Properties of Hydroxyapatite

Nowadays, serious environmental pollution demands enterprises to dispose waste water, especially for the printing, dyeing and nonferrous metal ones. Wastewater treatment technology is needed to improve urgently. Hydroxyapatite with large specific surface area and more microporous structure becomes a hot research topic in recent years for its strong adsorption ability. In this paper, the pollution situation, adsorption properties, adsorption mechanism, influencing factors and adsorption kinetic of hydroxyapatite are introduced.
