Abstract
Adsorption characteristics of La(III)-loaded chelating resin containing phosphonomethylamino groups for fluoride ion has been studied. Fluoride ion is effectively adsorbed on the column packed with La(III)-loaded resin at pH ranging 3.0-4.0. The retained fluoride ion has been released from the column by elution with 1 mol dm−3 sodium hydroxide solution without any leakage of the metal ion. The column can be used repeatedly after regeneration.Keywords
