Study of the Effect of Salt on the L-L Extraction of Carboxylic Acids (Formic; Acetic; Propionic) by Tributylphosphate (TBP)

Several previous experiments have shown that salt has a significant effect on the liquid-liquid extraction process, it has been used to enhance the "Salting-out" yield of this process. This is because the presence of salt affects the solubility of the elements present in an aqueous solution, in particular the solute. The addition of a salt to an aqueous solution introduces ionic forces that affect the equilibrium and directly influence the solute's distribution coefficient. We therefore studied the effect of three types of salt, namely Sodium Chloride (NaCl), Ammonium Carbonate ((NH4)2CO3) and Sodium Carbonate (Na2CO3), on the yield of liquid-liquid extraction processes for carboxylic acids (formic acid, acetic acid and propionic acid)...
