An ion-exchange procedure involving the selective retention of fluoride ions from aqueous
solutions containing 1, 5, 10, 20 and 50 mg F- L-1 using a new inorganic ion exchanger zirconium(IV)
oxide-ethanolamine ZrO-EA and its application to fluoride removal from potable water has been
described. A column equilibrium studies, batch process and different analytical parameters such as
concentration, pH and temperature for the quantitative recoveries of F- ion using ZrO-EA exchanger
were investigated and determined by an ion selective electrode. The effect of some other anions that
might be present with the analyte was also examined. The column experiments showed a quantitative
collection of fluoride at low concentration in water samples with more than 96% recovery
