摘要: The extraction of U(IV) by bis(2,4,4-trimethylpentyl) monothiophosphinic acid (CYANEX 302) in kerosene from nitric solution has been investigated under equilibrium conditions. effects the different parameters affecting process were studied and stoichiometry extracted species was elucidated. kinetics this also using a stirred Lewis cell. rate as well temperature separately investigated. results are interpreted reaction mechanism where is controlled chemical at interface rather than bulk phase.
