A mathematical model has been developed to explain the solubility of ionic liquids in hydrochloric acid solutions, with extraction constants being estimated. The study shows that the more hydrophilic the cation of the ionic liquid, the more hydrochloric acid is extracted.
A mathematical model to explain cations? solubility of both protic and aprotic ionic liquids in a wide range of hydrochloric acid solutions has been developed. The concept of this model is based on an assumption of the mineral acid extraction into the organic phase, formation of a salt there between an ionic liquid cation and chloride-anion due to ions recombination and partial salt back-extraction. The proposed approach allows estimating corresponding extraction constants. Comparison of calculated and experimentally measured solubility product constants shows that they are in good agreement. It has been determined also that the more the hydrophilicity of the ionic liquids? cation the more hydrochloric acid is extracted. This model has been utilized to facilitate analysis of thallium transfer into hydrophobic ionic liquids providing insights into the mechanism of metal extraction.
