Metal complexes of xanthan gum

lnteractions of selected paramagnetic transition metal salts [NI (II) Co (II) Cu (II) Fe(III), Mn(II)] with, xanthan gum are described. The conductivity, DSC/TG/DTG measurements, and EPR measurements produced evidence for the formation of the Werner-type complexes of metal central atoms with polysaccharide ligand. The polysaccharide hydroxyl groups and the carboxylic groups of xanthan gum were involved in ligation of the central atom.
