Abstract: The elimination of Ca2+ and Mad+ in diluted sugar solution by three kinds of larger pores canon exchange resins was sysematically studied. It was found that the Amberlite 252 resin was most effective for the elimination of Ca2+ and Mag + in diluted sugar solution and its exchange capacity was seriously influenced by PH and the flow velocity of sugar solution.

Key words: Large pores canon exchange resins, Dinted sugar liquor, Ca(2+) Mg(2+) Exchange capacity
