Solvent extraction of lanthanum and neodymium from phosphoric acid solution by OPAP diluted in mixed solvents

الملخص EN

Liquid-liquid extraction of La(III) and Nd(III), from 5.0 M phosphoric acid by OPAP in kerosene with different diluents such as benzene, toluene, o-xylene was studied at 25 °C.

The effects of different diluents with kerosene and their different ratios on the extraction process were investigated.

The data obtained are discussed in terms of dielectric constant as well as Hansen solubility parameters.
