Japanese Patent JP6736738

B2

To provide a separation method of a negative charge material which is capable of isolating the negative charge material by using fluorapatite excellent in acid resistance as a filler and adsorbing a large amount of negative charge materials with the filler from sample solution containing the negative charge material and contaminants composed of materials other than the negative charge material.SOLUTION: A separation method which separates a negative charge material from sample solution containing a target negative charge material and contaminants composed of materials other than the negative charge material has: a supply step which supplies sample solution containing the negative charge material, the contaminants and buffer solution in adsorption equipment 1 that fills an adsorption agent 3 composed of fluorapatite expressed by a chemical formula, Ca(PO)(OH)F[where x is equal to 0
