Abstract: For determination of iodine, dissolution or oxidation of an organic matrix by acid K-chlorate in dilute nitric acid to obtain non-volatile iodate immediately, is a method of choice. Optical emission spectroscopy is usually sensitive enough to control iodized table salt. Spectral interference by P upon the most sensitive I-emission line, e.g. in mineral feeds and marine algae, was overcome by co-precipitation of P with Al-or Fe hydroxide, leaving iodate (and also borate) in solution. After addition of Al or Fe …
