Ion-chromatographic determination of iodide in sea water with UV detection

Ion Chromatographic Analyses of Sea Waters, Brines and Related Samples

“…The first six papers listed in Table 2 describe methods for determining iodide in untreated sea water samples [20][21][22][23][24][25]. Brandao et al [20] used a post-column derivatization with N-chlorosuccinimide followed by a spectrometric detection at the wavelength 605 nm; in contrast to other authors who reported a direct spectrometric detection of iodide at the wavelengths between 210 and 226 nm.…”

Physicochemical properties of silica gel coated with a thin layer of polyaniline (PANI) and its application in non-suppressed ion chromatography

“…Special attention was paid for iodide anion because of their biological importance and difficulty in trace analysis caused the high concentration of chloride matrix in environmental and pharmaceutical samples [7,28,34]. Conductivity detection is preferred for anion analysis however obtained LOD value for iodide in this technique are insufficient (about 0.1 ppm) thus spectrophotometric, potentiometric or amperometric detection is recommended for their trace determination [35][36][37]. In our investigations, UV-vis detector was employed for the simultaneous analysis iodide and the other ions in single chromatographic run.…”

A fluorescence turn-on probe for iodide based on the redox reaction between cupric and iodide

“…Researchers have developed many fluoride probes [9][10][11][12][13][14][15][16]. By contrast, the fluorescent iodide probes are relatively fewer, although it is necessary to detect iodide in environmental samples as iodide deficiency in natural resources is implicated in the occurrence of endemic goitre in mammals [1,17,18].…”
