Abstract
A method of producing fluoroapatite by using a calcium-based compound containing calcium, hydrogen fluoride and phosphoric acid is provided. The method can be produced fluoroapatite having improved acid resistance by reducing an amount of an impurity derived from a raw material to a low or very low level, and ability capable of separating a large amount of a protein due to a large specific surface area thereof. Further, fluoroapatite having high acid resistance and a large specific surface area is also provided. Furthermore, an adsorption apparatus using such fluoroapatite is also provided.
