This paper presents the results obtained by treating wine with strongly and weakly acidic cation-exchange resins in the hydrogen or sodium from for the purpose of removing undesirable components from it selectively.The results obtained with a batch process in dicated that in point of selectivity the strongly acidic cation-exchange resin in the hydrogen form was superior to others, and the weakly acidic cation exchanger in the sodium form varied with the resin contact time for removing calcium and magnesium.With a column method, it was ascertained that the strongly acidic cation-exchange resins in the different forms (hydrogen and sodium) did not differ appreciably in their effects on wine for removing calcium and magnesium, but with regards to iron and copper ions, the sodium form did not show the seelctive power.Such being the case, strongly acidic cation-exchange resin in the sodium from is not suitable for the wines which are required to bo removed from iron and copper selectively.Cation-exchange resin of weaker acidic strength was also tested and then concluded as follows : The stronger the acidity of the resin is, the more suitable is its use in wine treatment, since the selective power is greater and the quality of products is better.
