【Abstract】 In the solution of 0.02mol/L KOH,calcium-morin complex has a sensi- tive polarographic wave,as shown by the single sweep polarography.The peak potential of its derivative appears at -0.75V（vs SCE）.A linear relationship between peak current and calcium concentration holds in the range of 2.5×10^-6 —2.0×10^-5mol/L.The detecion limit for clacium is 0.lμg/ml.This method has been successively applied to the determination of calcium in human serum.The properties of this wave has been studied.The complexing ratio of the complex has been determined to be 1:1.更多还原
