Abstract
The extraction behavior of Sm(III) and Nd(III) with
N,N,N?,N?-tetrabutyl-3-oxa-diglycolamide (TBDGA) in 70% kerosene-30%
n-octanol from hydrochloride acid wasstudied. The effect of hydrochloric acid
concentration, extractant concentration,and temperature on the distribution
of rare earth elementswas investigated. The extraction mechanism was
established and the stoichiometry of the main extracted species was confirm
to be SmCl3?2TBDGA and NdCl3?2TBDGA for Sm(III) and Nd(III), respectively.
The extraction distribution ratio decreases with an increase in temperature,
which demonstrates that the extraction reaction is exothermic. The IR spectra
of the loaded organic phase and free extractant were recorded and discussed.
