Kinetic study of zirconium (IV) extraction by two aqueous phases

Mohamed Amine Didi

Zirconium (IV) extraction from its aqueous solutions using polyethoxylated alcohols (CiEj) as a biodegradable non-ionic surfactant was investigated.
According to the given surfactant concentration, the extracted solute arrived at 88.1% for C13E10, in one step. The kinetic study shows that the model of diffusion of ions in the micelles controls the extraction of zirconyl by coacervate. The kinetic study shows that the film-diffusion controls the extraction of zirconyl by coacervate, using C13E10. The film-diffusion control and the model of diffusion of ions in the micelles controls the extraction of zirconyl by coacervate, using C12E10
