Determination of Fluoride in Antarctic Krill by Ultrasonic Extraction and Ion Chromatography

Abstract:

A method was developed for the determination of inorganic and total fluoride in Antarctic krill by using Ultrasonic Extraction and Ion Chromatography (IC). The analyte is separated by the anion exchange column AS-15 and detected with the conductive detector. The linear range of the calibration curve for fluorinion was 0.25 mg/L to 10 mg/L with a correlation coefficient of 0.9993, and the recovery of this method was 89.62% to 103.91%, and the RSD was lower than 7.09%, the LOD of this method was 0.008 mg/L and LOQ was 0.025 mg/L. Both inorganic and total fluoride in Antarctic krill were higher than GB 2762-2005, but they all much lower than ever reported.
