| Abstract: | Two colorimetric methods with different principles for iodine determination was studied The detection range, determination time and the method of debromine were improved Iodine in various kinds of fortified foods were determined by the suggested methods The lowest limits of determination were 0 005?mg/kg and 0 05mg/kg respectively The precision (RSD%) were <3% and <1% respectively And the average recoveries were (100 2±1 7)% and (98 3±1 7)% respectively The determination results of two methods showed satisfactory agreement with each other |
