Abstract:
The present invention provides a water purification material capable of selectively adsorbing phosphorus dissolved in wastewater, and also provides a water purification method employing the material. The water purification material comprises a composite metal hydroxide containing iron ions and calcium ions in its structure, and this composite metal hydroxide has a layered structure. In the water purification method of the present invention, the water purification material is brought into contact with wastewater so as to remove and recover phosphate ions in the wastewater.
