Summary

The isotopic dilution technique is used to determine the lithium content in three water samples and one solid sample extracted from four different localities in U.A.R. The results are as follows:
$$\begin{gathered} Karoon Lake163.92 \pm 0.78 \mu g/litre, \hfill \\ Ein Helwan349.50 \pm 6.86 \mu g/litre, \hfill \\ Ein Kabritea302.74 \pm 4.56 \mu g/litre, \hfill \\ Vermeculite Mica100.46 \pm 3.26 p.pm. \hfill \\ \end{gathered} $$
