Determination of iodide in seawater samples by ion chromatography with chemically-bonded poly(ethylene glycol) stationary phase
چکیده انگلیسی

An ion chromatographic method for the rapid and direct determination of iodide in seawater is reported. Poly(ethylene glycol) (PEG) groups were chemically bonded onto silica gel or C30-bonded silica gel via diol groups. PEG-bonded C30 binary phases allowed determination of iodide in seawater samples without any interference. Effects of eluent composition on retention behavior of inorganic anions have been investigated. Both cation and anion of the eluent affected the retention of analyte anions. The retention time of anions increased with increasing eluent concentration. The detection limit for iodide obtained by injecting 0.2 μl of sample was 13 μg l−1 (S/N = 3) while the limit of quantitation was 43 μg l−1 (S/N = 10). The present method was successfully applied to the rapid and direct determination of iodide in seawater with long-term durability.
