Effect of Different Parameters on Lithium Ion Transfer through PVDF-UIO-66 Cation Selective Hybrid Membrane via Electrodialysis Technique

Abstract:

This study aims to increase the efficiency of Li ion recovery via electrodialysis technique by manipulating several parameters. The membrane used for this study consists of a polymer matrix that acts as a backbone, and a metal organic framework (MOF) that acts as the cation selective agent. Polyvinylidene fluoride (PVDF) was chosen for this study due to its mechanical properties and chemical stability. UIO-66 was chosen as the cation selective MOF and prepared via hydrothermal method and characterized using XRD. The membrane matrix was synthesized using phase inversion casting technique. After casting, the membrane was characterized using XRD and FTIR to ensure that the MOF was successfully embedded. The investigated operation parameters are voltage applied, initial Li ion concentration, and time of operation. The tests were conducted at a selected value of each other controlled variable while manipulating only one variable at a time. The studied concentrations were 100, 200, 300, and 400 ppm, while the applied voltage varied from to 10 to 40 V with a 10 V step. The time parameter studeid was 1, 2, 3, and 4 hrs. This study aims to show the parameters’ effects on the recovery of the lithium ion. The highest recovery was recorded for each parameter.
