| Description | • Design and construction of prototype two-dimensional countercurrent chromatography (2D CCC) instrument that allows visualisation studies. • Details of the phase distribution, settling and mixing characteristics of two-phase mixtures, and phase retention within the coils for different solvent systems and operational conditions. • Ionic liquid based solvent system optimised by QUILL for metal processing exhibited unique and unexpected hydrodynamic behaviour in comparison to traditional biphasic solvent systems also investigated. • The results were used to understand the performance of CCC and to design ionic liquids for separations in different applications (including energy and pharmaceuticals). They also aid the design of scale up systems. |
| Exploitation Route | The results of this work may be useful in the design and operation of certain CCC instrumentation for ionic liquid based extractions in a wide range of applications in addition to metal processing. |

| Description | In the project we demonstrated that ionic liquids can be used as alternatives to organic solvents for the separation (extraction) of metals in countercurrent chromatography (CCC). We also showed that a new type of CCC that has a two-dimensional column (2D CCC) can result in efficient separations compared to the standard three dimensional CCC (3D CCC). In addition, 2D CCC allows the visual observation of the mixing and settling patterns of the liquids inside the coils of the column. These can help understand the separation performance of the column. Based on these studies we found that ionic liquids form different patterns compared to conventional solvents. These findings have helped identify ionic liquid systems that are suitable for the separation of metals for a wide range of applications (including spent nuclear fuel separations and healthcare. The detailed studies of the hydrodynamics in the column have helped the design of the scale up systems. |
