The determination of trace elements in silicate rocks by a combined spectrochemical-anion exchange technique

摘要: Abstract The paper describes an attempt to combine anionic exchange enrichment techniques with a spectrochemical method of analysis for the purpose determining several rare elements in silicate rocks, soils and meteorites. investigation has most part been confined which form chloro-complexes hydrochloric acid; notably Ag, Pb, Sn, Bi, Cd, Zn, Tl, Mo In. These may be absorbed on basic anion exchanger: after elution evaporation, residues are analysed quantitatively by d.c. arc method. ability determine trace single general operation is advantage procedure. combined procedure applied determination Tl Sn suite nineteen rocks including granite G-l diabase W-l, specimens gneiss sea-mud from Antarctic.
