Extraction and separation of W and rare earth from H2SO4 ...

2021-2-15  The La extraction first increased and then decreased with increasing sulfuric concentration. In the extraction process, N1923 is first protonated by reacting with the sulfuric acid according to Eq. and then can extract W and La. As sulfuric concentration was lower, the amount of sulfuric acid remained low and could not provide sufficient SO 4 2−.

Liquid–liquid extraction of yttrium using primene-JMT

Abstract The liquid–liquid extraction of yttrium(III) from sulfate medium using primene-JMT is investigated with regard to extractant concentration, diluent type, equilibrium pH and time, temperature, and extraction isotherm. Aliphatic kerosene diluents were preferred compared to aromatic diluents because of higher extraction, shorter equilibrium time and good phase separation.
