[Determination of 8 elements in Elaeagnus mollis by AAS].

Eight kinds of trace elements of Elaeagnus mollis were determinated with flame atomic absorption spectrophotometry method. The result shows that there is evident difference of the trace elements in different organs and growing stages. The trace element is plentiful in this kind of plant, specially in root, leaf and seed.

[Analysis of Ca, Mg, Fe, Mn, Cu and Zn in algae].

In this paper, we used flame atomic absorption spectrophotometry to determine the contents of Ca, Mg, Fe, Mn, Cu and Zn in 7 species of algae. The results showed that there were relatively rich Ca, Mg, Fe, Mn, Cu and Zn in the algae. The useful data were provided for algae as resource to be utilized.
