Two samples were analyzed for iodide: a synthetic sea salt and an iodized table salt. Freshly prepared table salt contained 92.4 μg/L of iodide, or 46 μg/g of iodide in the dry salt. Figure 2 shows the determination of iodide in table salt using the Dionex IonPac AS20 column and conductivity and UV detections.
7 Σεπ 2018 · This work proposes an alternative approach for the quantification of iodine in table salt samples, that combine the good accuracy and precision obtained by titrimetric methods with the convenience of using a spectrophotometer, using just a polyurethane foam and a scanner, trough digital image analysis.
Different salt iodine test methods need to be used depending on the form of iodine (iodate or iodide) used in fortification. The iodometric method for iodate will not detect the iodine content of a salt sample fortified with potassium iodide, and vice versa.
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.
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 · 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...
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.
