Extraction properties of new aminophosphinoxide compounds

Cherkasov R.; Garifzjanov A.; Leont'eva S.; Bazanova E.; Bazanova O. (2011)

Extraction of Sc(III) ions by new a-aminomethylphosphinoxides was studied. Preliminary experiments with acid solutions allowed for selection of low-basicity compounds, which demonstrated a poor coefficient of the acids ...
Liquid extraction of some rare earth elements with aminomethylphosphine oxides

Cherkasov R.; Garifzyanov A.; Bazanova E.; Davletshin R.; Leont'eva S. (2012)

Methods were developed of the solvent extraction from aqueous solutions of hydrochloric, nitric, and perchloric acids of the triply charged ions of rare earth elements including samarium, lutetium, dysprosium, neodymium, ...
Solvent extraction of some trace metals and iron with N-octyl-N,N- bis(dihexylphosphinylmethyl)amine

Cherkasov R.; Garifzyanov A.; Bazanova O.; Leont'eva S. (2011)

The processes were studied of the solvent extraction of the ions of triply-charged trace elements including scandium, indium, gallium, and yttrium, as well as iron, with N-octyl-N,N-bis(dihexylphosphinylmethyl)amine solution ...
