Optimum Ratio of Cations on Nuclear Sulfonic Acid Resin for Minimum Change in Composition of Resin-Treated Milk

Abstract
Equilibria between a strong sulfonic-acid ion-exchange resin (Amberlite IR-120) and major cations in milk was studied. Changes in ions may be minimized when milk is contacted with resin by placing mole fractions of cations in resin phase which will be in equilibria with milk. Equilibria are considered as a function of pH.
