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.
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.
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.
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.
9 Σεπ 2013 · Iodine levels in salt, urine, milk and serum provide information on the key marks used in the assessment of iodine nutritional status in populations. Microplate reading method, which...
There are a number of methods for testing the iodine content of salt, ranging from qualitative “spot” tests which are useful in field settings (see Chapter 10, Rapid Salt Testing Kits, for details), to more quantita- tive methods, such as iodometric titrations performed in laboratories for validation purposes.
