Some reconnaissance observations on the combined use of ion-exchange enrichment and spectrochemical analysis for the determination of trace constituents in silicate rocks

摘要: Abstract A reconnaissance investigation has been made of the possible combined use ion-exchange enrichment (cation and anion) spectrochemical analysis for determination several rare elements, notably Ag, Be, Bi, Cd, Cs, In, La, Mo, Nb, Sn, Pb, Tl, Y Zn, in silicate rocks allied materials. Observations which have carried out on granite G-1, a specimen Cape granite, diabase W-1, indicate that many these elements should be easily detected wide variety soils. The scope procedure seems to immense it is evidently determine single operation; particularly useful investigating general geochemistry Bi.
