In this work, a novel room temperature ionic liquid1- methylimidazolium di(2-ethylhexyl) phosphonic acid was synthesized, characterized and tested as extractant in the Dysprosium(III) liquid-liquid extraction. The effects of parameters such as contact time, aqueous to organic phase’s volume ratio, metal concentration, ionic liquid concentration, pH levels, ionic strength, and temperature were reported.
The extraction efficiency of Dysprosium(III) ions was increased by increasing the concentration of ionic liquid and was negatively influencedby the presence of CH3COONa salt in the aqueous phase. The results showed also that theextraction process was feasible, spontaneous and most favourable at higher temperature.
