    摘要: A method for removing phosphate ion from an aqueous solution containing phosphate ion using a resin loaded with a hydrous oxide of an amphoteric metal ion. The resin loaded with a hydrous oxide of an amphoteric metal ion is produced by combining a resin with at least two bed volumes of an aqueous solution containing a salt of the amphoteric metal ion, and having a metal ion concentration of at least 5%, and then treating with an aqueous alkali metal hydroxide solution.
