Wet Phosphoric Acid (WPA), whose concentration is typically ranging between 4 and 7 mol.L-1, is a strategic source of uranium that can be exploited in spite of its low uranium content (0.1-0.4 g.L-1) and the strong complexing power of the phosphoric medium.Numerous studies concerned the development of synergie mixtures of extractants for the recovery of uranium (Ⅵ) from wet phosphoric acid but most of the extractants are not sufficiently selective against iron.
