Kinetic Study Of Zirconium (iv) Extraction By Two Aqueous Phases
Authors : Didi Mohamed Amine .
Abstract
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 C13E, 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 C13 E10. The film-diffusion control and the model of diffusion of ions in the micelles controls the extraction of zirconyl by coacervate, using C12 E10
