Abstract

The invention discloses an iodide ion detection kit based on iodine catalyzed arsenic-cerium reaction under the acidic condition and taking a Ferrion solution as a redox indicator. The kit comprises adigestion solution, a reducing agent, an oxidizing agent and an indicator; an ammonium persulfate or acidic potassium permanganate solution serves as the digestion solution; the arsenious acid solution serves as the reducing agent; a tetravalent cerium solution serves as the oxidizing agent; and a Ferroin reagent solution serves as the indicator. An iodine standard series solution is prepared, and the ammonium persulfate or acidic potassium permanganate solution is used as the digestion solution, so that the defects of dense smoke and explosiveness of chloric acid digestion are overcome. Thedetection kit also has the advantages of being simple, rapid, specified, sensitive and accurate, can be widely applied to the fields in which the content of iodide needs to be detected, and in particular, to urine iodine and water iodine detection in the fields of hygiene inspection and medical inspection.

Description

technical field

[0001] The invention belongs to the technical field of iodine ion detection, relates to reagents and detection methods for detecting urine iodine and water iodine in the field of sanitary inspection and medical inspection, and specifically relates to a method based on iodine catalyzing the reaction of arsenic and cerium under acidic conditions and using Ferrion solution for oxidation Iodide Ion Assay Kit for Reducing Indicators. Background technique

[0002] In the field of health and medicine, the detection of iodine ions is mainly the detection of urine iodine and water iodine. Urinary iodine is an important indicator for the monitoring of iodine deficiency disease prevention and control and the evaluation of iodine nutrition level in the population, which has been widely used at home and abroad. The urinary iodine level of the population can reflect whether the iodine intake of the population is iodine deficiency, iodine appropriate or iodine excess. The ...
