Abstract: The purification of casein phosphopeptieds (CPPs) with alkali anion- exchanger was studied.The results were as follows:the purifying effects of the GM201 were best,the optimum eluting parameters were:0.2mol/L hydrochloric acid and 0.3mol/L salt elution at 45℃ .On this condition almost 80% CPPs was recovered and the purity of CPPs was up to 4.7~ 4.9 for N∶ P.
