Abstract
This paper studied some equilibria in the Nd3+–water–nitric acid–TODGA (N,N,N,N-tetraoctyl diglycolamide)–CO2 system and the efficiency of extraction of Nd3+ ions from aqueous solutions into the supercritical (SC) CO2 phase at 313–353 K and 18.0–40.0 MPa. It was shown that, in the absence of TODGA, Nd3+ ions do not pass into the SC phase. The extraction efficiency increases with decreasing temperature and with increasing nitric acid concentration CNA in the aqueous solution. At 313 K, CNA > 1.5 mol/L, TODGA content not less than 100 mol/g-at. Nd, and CO2pressure ensuring complete dissolution of TODGA (19.0 MPa), Nd3+ completely pass into the SC phase. With increasing content of neodymium ions in the system, the pressure and amount of CO2 required for complete dissolution of TODGA increase. This is likely to be due to a decrease in the intensity of intermolecular interactions in the SC phase during the passage of polar Nd complexes with TODGA and nitrate ions into it.
