哺乳妇女血、乳中三种元素含量检测

Determination of Three Kinds of Chemical Elements in Blood and Milk of Breast-fed in Women

研究了哺乳期母体内血、乳中锌、铁、钙三种元素含量的检测。探讨了用一定量的基体释放剂 ,取少量血液、乳液经大倍数稀释 ,直接于原子吸收仪上进行测定。此法快速、准确、实用。

The purpose of this research is how to know quantity of important and essential chemical element,such as Zn,Fe,Ca which are in bolld,milk of mother during breast-fed period.The big physical volume,strong acid was adopted to resolve the sample for increasing the digesting degree of the gain sample.But the strength of work is big,the interference is large.The pollutionis easy, the blank of worth is high,the depletion that has great capacities,the effect factor is complicacy and the result is unsteady.The fixed amount of release was used in a little amount of blood,milk through the big multiple dilutions,then determined by atomic absonbtion spectrometer.This method in rapid,accurate,and practical.
