The semi-quantitative estimation of the salt iodine by using a rapid test kit (RTK) is based on the reaction between starch and iodine to form starch-iodine complex. This test solution contains an acidic buffer and a reducing agent, which convert potassium iodate (KIO 3) to elemental iodine (I 2).
20 Μαΐ 2016 · The median and interquartile range iodine concentration in salt was 2.9 mg/kg (IQR: 2.4-3.7). The results show that only 25 % of households use iodized salt. The recommended iodine concentration in salt of 15–40 mg/kg was met only in 4.5 % of salt samples. The bulk salt is used by 8 % of households.
1 Φεβ 2010 · Iodine in salt is determined quantitatively by the titration method, colorimetrically by the WYD iodine checker or by a technologically advanced potentiometric method. Worldwide, titration is the method of choice because of its accuracy, ease of operation and low cost.
1 Ιουν 2017 · Iodine in salt is determined quantitatively by the titration method, colorimetrically by the WYD iodine checker or by a technologically advanced potentiometric method.
The iodine content of iodated salt samples is measured using an iodometric titration, as described by DeMaeyer, Lowenstein, and Thilly, (1979). The reaction mechanism can be considered in two steps (See Box 1): Reaction 1: Liberation of free Iodine from salt • Addition of H2SO4 liberates free iodine from the iodate in the salt sample.
4 Δεκ 1996 · Based on this information, this document summarizes current WHO, UNICEF and ICCIDD recommendations concerning iodine levels in salt, risk of associated iodine-induced hyperthyroidism, and requirements for monitoring both iodine status and adequacy of iodine levels in salt.
9 Σεπ 2013 · This paper presents a review of the most common methods used to determine iodine levels in salt and biological samples. Evidence Acquisitions: We conducted a literature review of published...
