A wine which contains copper sulfate (as 34 p.p.m. of Cu) was treated with cation exchanger at a flow rate of 5 v.v.h. in hydrogen on potassium cycle and also with anion exchanger in tartrate cycle.The results indicate that in H-cycle the cation exchanger has a greater capacity for removing copper than in the other cycles. Adsorption efficiency in H-cycle was 91.2%, when about five times its volume of the wine had been passed through the exchanger (Table 2), and 1.5 mg of copper was adsorbed per ml of resin.With the H-cycle of cation exchanger the wine became slightly sour in taste, but this sourness was removed by treating with anion exchanger (Table 1). With the K-cycle of cation exchanger the wine became saltish in taste but, with the anion exchanger (tartratecycle) rough in flavor and taste.
