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.
21 Νοε 2013 · Iodine (in the form of iodide) is added to table salt to help prevent iodine deficiency. Since the 1980s there have been efforts to have universal salt iodization.
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).
Various methods are available for testing the iodine content in salt. One such method is the rapid salt test-ing kit, which is a field-friendly, inexpensive, highly sensitive test. The test qualitatively or semiquantita-tively detects iodine in salt.
The main indicator adopted to track universal salt iodization has been the coverage of adequately iodized salt in households. Rapid test kits (RTK) have been included in household surveys to test the iodine content in salt.
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.
Introduction. Have you ever noticed that the salt you’re using says it’s “iodized”? Iodine is a micronutrient, which means we need it in small quantities to be healthy. Because iodine is relatively rare in many people’s normal diets, it’s added to table salt.
