Abstract
In this work the extraction of dioxouranium(VI) from aqueous nitric acid solutions (3M) into TBP/ionic liquid mixtures (30% v/v), is studied in intensified small scale separator channels of different sizes. High speed imaging is used to obtain the important hydrodynamic features of the flow (i.e. plug velocity and plug length) which are related to mass transfer and extraction efficiency. It was found that the overall mass transfer coefficients varied between 0.07 and 0.24 s−1 and increase by decreasing the channel size. The extraction efficiency was also affected by the channel size. A decrease in channel size leads to higher extraction efficiencies, while for a certain channel size the extraction efficiency decreases by increasing the mixture velocity.
