| Abstract: | Basic ashing method was used to digest the hair sample. Impurities were separated from iodine in neutral solution by centrifugation. An iodine determination of human hair was carried out in an acid solution by catalytic potentiometry. The recovery was 98.6％ and the coefficient of variation(CV)8.7％. The determined average content of iodine was 0.93μg/g for the hair samples of 20 boy students in one class who came from the area of middle iodine content. |
