Computational simulation and modelling of uranium extraction using tributylphosphate through membrane extractor

Abstract Non-disperse solvent extraction is an effective technique for the extraction of metal ions from aqueous solution. In this study, uranium extraction using n-dodecane solvent containing tributylphosphate extractant in a membrane contactor was investigated. A 2D mathematical model was develope...
