Determination of iodine in human milk and infant formulas.
The aim of this study was to develop a method to determine iodine in human milk and infant formulas using ICP-MS. The milk samples were digested using an alkaline digestion (5% NH(3), 45 W, 2 min and 30s), and the method was validated using a certified reference material (CRM) BCR CRM151. On the other hand the milk was separated in three fractions, whey, fat and caseins using ultracentrifugatio...
متن کاملIodine Determination in Raw Cow's Milk in Iran
Iodine is an essential trace element in the human diet. The following work presents the latest information concerned with iodine determination in raw milk, in Iran. Iodine content of milk was determined by Sandell-Kolthoff method where the samples were taken from Holstein dairy cows, in Shahrkord, the central part of Iran. Thirty six samples were taken from transportation tanks in semi industri...
متن کاملDetermination of iodine concentration in human milk, cows' milk and infant formula and estimation of daily iodine intake of infants.
A simple and sensitive kinetic-catalytic method was used for the determination of iodine concentration in human milk, cows' milk and infant formula. The method, based on the catalytic effect of iodine on the redox reaction between CeIV and AsIII, was first described by Sandell and Kolthoff. The calibration curve was constructed by plotting absorbance of CeIV after a known time versus iodine con...
متن کاملDetermination of total iodine in urine, stool, diets, and tissue.
13ETIiRMINATION of total iodine in various materials has become of increasing interest, especially in nutritional studies. Several methods are available for such determination. Many of them have been principally concerned with the protein-bound iodine fraction in serum (1, 2). Other methods for iodine determination have appeared from time to time. Mathews et al. (3) have proposed a method which...
