Solvent extraction of Ba2+, Pb2+ and Cd2+ into nitrobenzene by using strontium dicarbollylcobaltate in the presence of tetraethyl p-tert-butylcalix[4]arene tetraacetate

Original language description

Extraction of microamounts of calcium, strontium and barium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of dibenzo-18-crown-6 (DB18C6, L) has been investigated. The equilibrium data have been explained assuming thatthe complexes HL+, ML2+, ML22+ a MHL23+ (M2+ = Ca2+, Sr2+, Ba2+) are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.

Czech name

Extrakce Ba2+, Pb2+ a Cd2+ roztokem strontnaté sole dikarbollylkobaltitanu v nitrobenzenu za přítomnosti tetraethyl p-terc-butylkalix[4]aren tetraacetátu

Czech description

Byla sledována extrakce mikrokoncentrací Ca, Sr a Ba roztokem kyselé formy dikarbollylkobaltitanu (H+B-) v nitrobenzenu za přítomnosti dibenzo-18-crown-6 (DB18C6, L). Bylo zjištěno, že do organické fáze přecházejí komplexy HL+, ML2+, ML22+ a MHL23+ (M2+= Ca2+, Sr2+, Ba2+) a spočteny hodnoty rovnovážných extrakčních konstant a konstant stability nalezených komplexů v nitrobenzenu.
