    • The invention relates to a method and kit for quick and low-cost determination of the iodide ion content, which can be used not only to detect the possible iodine deficient conditions but also to estimate the iodide ion concentration of aqueous solutions. The present invention relates to a method for the determination of iodide ions in an aqueous solution, comprising the steps of: a) providing a liquid sample for which iodide ion concentration has to be determined, b) adding at least one drop of aqueous solution of metal ion to the liquid sample of step a) wherein the metal ions selectively precipitate with iodide ion under normal conditions; c) shaking the liquid sample of step b) and waiting for 1 to 5 minutes, preferably 3 minutes; d) repeating steps b) and c) until the precipitation is clearly visible to the naked eye in the test solution; e) recording and summing up the number of drops; and f) determining the amount of iodide ions based on the number of drops. The present invention further relates to a kit for determination of iodide ions in an aqueous solution. The kit according to the invention comprises a sample vessel, a vessel equipped with a dropper wherein the said vessel contains a metal salt solution which selectively precipitates with iodide ion content under normal conditions and an instruction for describing the method of determining the iodide ions in aqueous solution.
