Optimization of Indium Recovery and Separation from LCD Waste by Solvent Extraction with Bis(2-ethylhexyl) Phosphate (D2EHPA)

Figure 10

The effect of temperature on the extraction equilibrium of Fe(III), In(III), and Sn(IV). The aqueous phase was 0.1 M HCl and the organic phase was 0.1 M D2EHPA/kerosene, .
