Abstract
The principle of this method is to combine the metals with organic reagents, then extract them with non-polar solvents, and determine them by making chromatograph with adequate adsorbents. Dithizone is used to determine Hg, Cd, Bi, Ag, Cu, Zn, Ni, Co, Tl, Pb, Pd and its isotopes, Pt group, Au, etc. Diphenylcarbazone is applicable to determine Hg, Cu, Zn, Ni, etc. Xanthate is useful to determine Mo, Cu, Ni, Co, etc. α-orβ- Nitrosoβ- orα-naphthol is used to determine Fe, Co, earth acids etc. Diethyldithiocarbamate is used to determine Mo, Cu, Ni, Co, Fe, etc. Oxine series are useful to determine Cu, Ni, Fe, V, rare earth etc. α-indolcarbonic acid is applied to determine Fe, Co, rare earth etc. Acethyl acetone is used to determine Th, Fe, etc. Some other organic reagents were used moreover. There are some elements of which necessary condition for quantitative determination is still not decided or the order of adsorption is indefmite. As adsorbents alkaline, neutral or acid alumina, diatom earth and aluminate, magnesium carbonate, calcium carbonate, urea formaline resin, heulandite, mordenite, desmine, chabazite etc· were used. With this method the author tryed severd determinations on rocks, minerals, mineral springs, organisms etc. The contento; of Cu, Zn, Ni and Co in rocks were 0.007, 0.008, 0.002 and 0.004% respectively. Cobalt content proved to be more than that of nickel. The mercury content of rocks was proved to be 10 times more to Clarke number, bismuth and cadmium content as same as or less than Clarke number. Silver in plants, soil and mineral waters, platinum in serpentine; mercury, cadmium, bismuth etc in mineral waters, trace heavy metals in organism, etc were determined. Radium B and Thorium B in hot spring waters were used as tracer. As organic solvents methyl-, ethyl-, butyl-, amy1-, octyl alcohol, dioxan, benzol, toluene, xylol, petroleum ether, ether, ethylacetate, chloloform, carbon tetrachloride, carbon disulfide etc were applied.
