Cyclic solvent extraction with OIDMDPPA and oxalate stripping to recover purified H3PO4, Al(OH)3 and battery grade FeC2O4·2H2O from wet-process phosphoric acid
Key Points
The method enables recovery of high-purity H3PO4 and Al(OH)3 from wet-process phosphoric acid, improving resource use.
Utilizing cyclic solvent extraction and oxalate stripping, the process isolates aluminum hydroxide effectively.
Analysis reveals that iron(II) oxalate can be obtained from the same phosphoric acid source, offering multiple product recovery.
The findings suggest enhanced sustainability in phosphoric acid processing, optimizing chemical recovery methods.
