Adsorption of Rare Earth Ce³⁺ and Pr³⁺ Ions by Hydrophobic Ionic Liquid

Table 6

Influence of salt ionic strength on the elimination of Ce (III) and Pr (III) ions from the solution (time- 30 min, dose- 0.5 mg g⁻¹, and temperature- 303 K).

Ionic strength (mol L^−1)	Salt	Sorption capacity (mg g^−1)
