Abstract:
A modified method of Watkinson's was used for the kinetic colorimetr-ic determination of iodine in high iodized egg with I~ catalytic arsenous acid and cerous sulfate. The lowest limit determination for iodine was 0.01ug.Coefficient of variation was 4.3-7.9% and recovery rate was 90.6-95.9%. As the I- catalytic action was so fast, that the operation time must be restricted to optimize the better determination.
