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.
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.
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).
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.
11 Μαΐ 2016 · 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.
1 Ιαν 2016 · The next section describes the main methods for monitoring iodine levels in iodized salt and their strengths and weaknesses for applications in low-resource settings; we then focus our discussion on a recently developed paper test card, using it as a case study for the early stages of transitioning a technology from laboratory to field implement...
Determine the performance of a laboratory spectrophotometric method and three single-wavelength spectrophotometric devices for quantifying iodine in salt against the standard iodometric titration method. Compare the analytical accuracy and precision, simplicity of use, and cost.
