Abstract
This study was demonstrated to determine the concentration of iodine obtained from different regions of Al-
Muthanna Governorate in different labeled salt. 136 samples including 10 commercial brands were collected. The iodine
contents of the samples were measured by both the iodometric titration process and spot-testing kit. The results displayed
that 36.7% of all samples are inadequate iodine content. The quantitative analysis showed that 31.6% and 46.3%
are iodine inadequate salts with content less than 15 ppm of salt samples commercialized in urban and rural regions,
respectively. Also, there is a significant difference in iodine concentrations between packaged and bulk salt, besides, all
samples of bulk salt were found in rural areas. a comparative study was made between results obtained from iodometric
titration and spot-testing kit method, and both methods showed a nearly similar proportion of salt samples with iodine
≥15 ppm (61.8% by kit and 63.3% by titration). These results indicate that the titration technique is essential for
quantitative purposes. However, the spot-kit method is dependable for semi-quantitative evaluation of iodine content
and it can be utilized for monitoring the quality of iodized salt obtainable in the community.
