Adsorbents based on transition metal salts were
proposed for the retention of low-molecular polar
organic compounds more than 40 years ago [7]; however, the potentials of these adsorbents were characterized incompletely. It was found recently that, among
the studied several dozens of transition metal salts, the
highest adsorption affinity to low-molecular oxygencontaining organic compounds (methanol, ethanol,
and acetone) was demonstrated by adsorbents based
on cobalt(II) chloride.
