Dissolution of Metal Oxides in a Choline Chloride–Sulphosalicylic Acid Deep Eutectic Solvent

A choline chloride–sulfosalicylic acid deep eutectic solvent (DES) is proposed for dissolving the oxides Co(II), Cu(II), Zn(II), Fe(III), Ni(III) and Mn(III). An experimental study of the influence of the dissolution time, solid : liquid mass ratio, temperature, and molar ratio of choline chloride a...

Summary:A choline chloride–sulfosalicylic acid deep eutectic solvent (DES) is proposed for dissolving the oxides Co(II), Cu(II), Zn(II), Fe(III), Ni(III) and Mn(III). An experimental study of the influence of the dissolution time, solid : liquid mass ratio, temperature, and molar ratio of choline chloride and sulfosalicylic acid on the dissolution of metal oxides in the proposed DES has been carried out. The mechanism of dissolution of the investigated metal oxides has been established. It is shown that choline chloride–sulfosalicylic acid DES can potentially be used for the efficient leaching of metals from components of spent chemical power sources.
