Abstract

A simple on-site column analysis/solid-phase extraction method for the determination of fluoride in water was developed based on the combining of the analysis using a column collection and solid-phase extraction, followed by spectrophotometric determination. The column was prepared by packing silica gel loaded with a zirconium-alizarine red S complex. In on-site column analysis, the concentration of fluoride was measured by the length of a colored-band (white band) formed in the column, which was made by ligand-exchange reaction between fluoride and alizarine red S bonded with zirconium, when the fluoride in water was collected by the column. After the collected fluoride in the column was easily eluted by elution (sodium hydroxide solution), its spectrophotometric determination was made with good precision. This method was useful for simple on-site determination using simple on-site column analysis, and then a solid-phase extraction method gave precise determination values. The established method was successfully applied to environmental water samples.
