Optimization of Indium Recovery and Separation from LCD Waste by Solvent Extraction with Bis(2-ethylhexyl) Phosphate (D2EHPA)
Figure 11
Schematic diagram of a potential process for the recycling of indium from LCD glass, showing an extraction, scrubbing, and stripping step. The aqueous phase was 1 M H2SO4 (extraction and scrubbing) and 1 M HCl (stripping); organic phase is 0.25 M D2EHPA diluted in kerosene with 2% 1-decanol.
