[Determination of chromium, manganese and nickel in six biological agents]

The determination of chromium, manganese and nickel in biological agents has obtained by flame atomic absorption spectrometry. The results show that three trace elements of body necessary are the most rich in ant factor injection liquid. The chromium content is slightly lower in the brain cell activator injection liquid, the nickel content is slightly lower in the shift factor injection liquid and the manganese is the lowest in the marrow factor injection liquid. In this paper, we have studied three trace element contents in six biological agents. It provides, useful data for clinical treatment to some trace-element-lacking diseases.
