Solvent extraction equilibria of magnesium(II) and calcium(II) (M^<2+>) in aqueous 1mol dm^<-3> sodium chloride solutions with 1-phenyl-4,4,4-trifluorobutane-1,3-dione(benzoyltrifluoroacetone, Hbfa) into carbon tetrachloride have been studied at 298 K in the absence and presence of tetraalkyl ammonium(R_4N^+), where R- is ethyl-, propyl-, or butyl- group. The extraction of magnesium(II) was always better than calcium(II). A chemical species NaM(bfa)_3, was extracted into the organic phase and R_4NM(bfa)_3 was also extracted if R_4N^+ ion was present and the longer the alkyl chain(R) in R_4N^+, the better the extraction otherwise identical.
