Abstract
A method of the ion chromatographic determination of fluoride ions in urinary stones has been
developed. Sample preparation of solid mineral–organic samples includes dissolution in concentrated
hydrochloric acid, dilution with deionized water, and the elimination of excess calcium and magnesium cat
ions by adding a KU2 sulfo cation exchanger in the Hform to samples and filtration through a membrane
filter. Anions were separated on a Shimpack ICAIS anionexchange column (100 × 4.6 mm) with elution
with a mixture of 2.0 mM phthalic acid and 1.2 mM sodium hydroxide (pH 3.5). The linearity range of the
fluoride ions in the obtained solutions of urinary stones with conductometric detection was 0.01–300 mg/L,
the limit of detection calculated by the 3s-test was 0.004 mg/L. The quantitative determination of fluoride
ions in 20 samples of urinary stones was performed; in 80% of cases the presence of fluorides in the stones at
a level from 0.01 to 4 mg/g of the stone was detected. The average concentration of the fluoride ions was
0.3 mg/g of stone. For 20% of the samples an elevated concentration of fluoride ions compared to the average
one was found.
