Abstract

The analysis of fluoride in atmospheric samples poses challenges to current available methods. Ion chromatographic methods often suffer from interferences due to elution of die fluoride peak in the water dip and coelution of weakly retained organic acid anions. A separation system using a macrocycle-based ion chromatographic column provides a fast, effective method for die separation of fluoride in complex matrices. The macrocycle-based system shows better resolution of fluoride than traditional ion chromatographic methods, separating fluoride from boththe water dip and the organic acid anions. Isocratic elution with a hydroxide eluent allows for a detection limit of 0.15 muM with a linearresponse between 0.4 and 150 muM. Results compare favorably with known values and those obtained by ion selective electrode analysis.
