Test Method A is intended for use on all brackish waters, seawaters, and brines that contain appreciable amounts of iodide or bromide ions or both. Test Methods B, C, and D, because of their rapidity and sensitivity, are recommended for the analysis of brackish waters, seawaters, and brines in the field and in the laboratory. method for the determination of iodine was desirable. Elmer (1) gives an excellent critical review of the existing methods for iodine determination up to Kirk (2) reviews the present methods and techniques for microanalysis, including iodine. The methods () entailing distillation.   The Determination of Iodine, Iodate, Iodide and Traces of Bromide in Waters (Tentative Methods) (Methods for the examination of waters and associated materials) by Department of the Environment 3 editions - first published in

An iodide ion is the ion I −. Compounds with iodine in formal oxidation state −1 are called page is for the iodide ion and its salts, not organoiodine everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments ide, iodine deficiency affects two billion people and is the leading preventable cause of Beilstein Reference: determination of iodate (IO 3-) in table salt and sea water. The proposed method is based on the reaction of iodate with potassium iodide in an acid medium to liberate iodine. The liberated iodine bleaches the blue color of methylene blue and is measured at nm. This decrease inCited by: 1. Iodide does not interfere with the determination. Iodide is oxidized to iodate by hypobromite. After destruction of the excess hypobromite, the potentiometric titration (of the iodine released from iodate) is carried out with sodium thiosulfate solution. Bromide does not interfere, even in great excess. Linear Starch-Iodate Reagent Selective for Iodide Ion.

Provides a simple qualitative scheme for the separation and identification of chloride, bromide, and : Marvin Wayne Hanson. Potassium iodide. Any C.P. grade of iodate-free iodide may be used. Mallinckrodt’s potassium iodide Neutral has been found satisfactory. Starch indicator. A per cent soluble starch solution pre- served with 1 mg. of mercuric iodide per cc. of solution is used (Kolthoff). The method was applied to the determination of iodate in iodized table salt and free iodide and total iodine in sea-water, and to spiked samples when the recovery was in the range % (RSD.
