Field determination of iodide in water

Chemical species

“…Hydrogen peroxide was measured by fluorometry based on the oxidation of acetaminophen by hydrogen peroxide (Jie et ai., 1995). Iodide, free iodine, and total iodine were measured in water by a simple and fast spectrophotometric method (Chandrawanshi and Patel, 1995). (1995) developed a disposable amperometric sensor for hydrogen peroxide.…”

Flow analysis determination of iodide atnanogram levels in water

“…Hence, the expected number of Fe(III)-SCN--CP / that can be destroyed by one mole of iodide or iodate should be 14. The validity of the present method was checked with a spectrophotometric method, which was based on oxidation of Iinto 12 with NaNO, preconcentration of I into toluene and reaction of the extract with brilliant green in sequence having detection limit 4 ng I-/ml water [5]; and an ion chromatographic method. The methods were applied for the analysis of total iodide to surface, ground and rain water; the results obtained by these three methods were comparable, see table 2.…”

“…Many methods (for example spectrophotometric, catalytic, ion-selective and ion chromatography) have been reported for the characterization of iodide in water [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The conventional spectrophotometric methods consume large amounts of reagents and samples with very poor sample analysis rates [2][3][4][5]. Iodide is usually determined through its catalytic effect on the Ce(VI)-As(III) system, either by measuring absorption at 405 nm or the fluorescence at 260 and 360 nm.…”
