Die Verwendung von n-Tributylphosphat als Extraktionsmittel und als Lösungsmittel in der Papierchromatographie

Extraction

“…Systematic metal ion extraction from HC1 and other mineral acids into trioctylphosphine oxide has been described (331). The use of TBP-HC1 systems has been extended to paper chromatographic methods for 27 metals (577). Values of distribution ratios could be calculated from the Rf value.…”

Chromatography

“…The addition of EDTA to solvent systems may reduce tailing (423, 529). Bis(2-ethylhexyl)phosphate (1181), tributyl phosphate (277,711,1103), and trioctvlphosphine oxide (249,340) are also used in partition chromatography on paper.…”
