The concurrent analysis of 14 kinds of metals, Hg, Bi, Cu, Zn, Sn, Mn, Fe, Co, Ni, Cd, Pb, Al, Be and Cr was made by the combination of dithizone extraction and oxine, 2-methyloxine extraction and silica gel thin-layer chromatography. The metals, Hg, Bi, Cu, Zn and Sn were extracted from the sample water by dithizone at pH 3,and Mn, Fe, Co, Ni, Cd, Pb and Sn at pH 9. After extraction with dithizone, the sample water was subjected to oxine extraction to extract Al, Be and Cr at pH 8. The metals in dithizone and oxine, 2-methyloxine extracts were taken up into 0.5 ml of 10 N HNO_3 and 3 N HCl, respectively. Separation of the metals in the acid extracts was made by thin-layer chromatography as in previous work. Using the methods here established, analyses for metals were performed on several sea and river waters obtained in Chiba prefecture.
