Separation and Determination of Fluoride Ion by Using Ion Exchange Resin Loaded with Alizarin Fluorine Blue(Analytical,Chemical)

Description

A new functional resin for the selective collection of fluoride ion was prepared from anion-exchange resin and lanthanum complex of Alizarin Fluorine Blue (AFB-La). The resin loaded with AFB-La was effective for the selective adsorption of fluoride ion in batch and column operations. Fluoride ion adsorbed could be eluted completely with a small volume of 1 M sodium hydroxide, and the concentration of fluoride ion thus concentrated in the eluate was determined by using an ion selective electrode. The resin could be regenerated by washing with water and used repeatedly without functional deterioration. A satisfactory result was obtained by the use of this resin in the determination of fluoride ion present at concentrations lower than that which can be determined directly by the ion selective electrode method. The interference caused by common cations and anions was not serious except for Al^<3+> and Fe^<3+>
