A chromatographic method using an ion exchange column has been developed for the determination of the iodine content in biological materials, foods, fodders and mineral premixes. The method is based on the reaction between iodine and tyrosine resulting in the formation of 3-iodotyrosine and 3,5-diio

A new development in separation science is the application of liquid ion exchangers. For the separation of metal ions, additional complexing in the aqueous phase can be favourable in some instances. The best method for increasing the efficiency of a separation is to impregnate an inert support with
