Abstract

Results of the extraction separation of binary mixtures of histidine, proline, and methionine using water-soluble homo- and copolymers with different molecular weights are presented. The recoveries and separation factors in the systems methionine–proline and histidine–proline are calculated. Amino acids were quantitatively determined by spectrophotometry using their intrinsic absorption in the UV spectral region. The efficiency of amino acid separation was increased using systems additionally containing chloride ions, which facilitate complex formation.
