【 摘 要 】

An ion-exchange procedure involving the selective retention of fluoride ions from aqueoussolutions 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 beendescribed. A column equilibrium studies, batch process and different analytical parameters such asconcentration, pH and temperature for the quantitative recoveries of F^- ion using ZrO-EA exchangerwere investigated and determined by an ion selective electrode. The effect of some other anions thatmight be present with the analyte was also examined. The column experiments showed a quantitativecollection of fluoride at low concentration in water samples with more than 96% recovery.
