Abstract

It is shown that the concentration of free iodine in samples of iodinated fatty-acid esters can be measured using the electronic absorption spectra of their solutions in ethanol. The method proposed is rather simple in use and highly sensitive, allowing detection of presence of less than 10 ppm of free iodine in iodinated compounds. It is shown using the example of Lipiodol that this makes it possible to easily detect small amounts of free iodine in samples containing bound iodine in concentrations down to 40 wt %.
