Skimmilk containing Sr ~ and Ca ~ was left in contact with Dowex 50~V-X12 in the calcium form for periods of 1, 10, 60, and 120 nfin. Apparent equilibrium was reached between the 1-and 10-min. periods. A dosed milk-resin ratio study showed that as the ratio increased, the percentage of removal of Sr ~ and Ca ~ decreased. The percentage removal ranged from a high of 94 and 93 for Sr ~ and Ca "~, respectively, at a milk-resin ratio of 2, to a low of 21% Sr ~ and 16% Ca '~ at a milk-resin ratio of 200. At a milkresin ratio of 2, 4.27% of the resin capacity was utilized and at a ratio of 200, 73.6% was utilized for exchange of Sr and Ca.
