Fluidic systems for investigation of single and multiple ion-exchange resin particles

Popis výsledku v původním jazyce

he research concerning electroseparation processes such as electrodeionization and electrodialysis mainly focuses on characterization and optimization of ion-exchange membranes as major functional components of the aforementioned processes. These membranes often consist of several components and are then regarded as heterogeneous. The major components are: (i) ion exchange resin (functional component), (ii) polyethylene or polypropylene (binder), and (iii) polymeric fibers (mechanical stability). While characterization of heterogeneous membranes does not present any technical challenge and is carried out on a daily basis in many laboratories around the world, characterization of single ion-exchange resin particles has not even been attempted, at least to the authors' knowledge. In this work we embarked on developing a fluidic system integrating single or multiple ion-exchange particles that allows electrochemical characterization of the resin particles. This electrochemical characterization is based on measurement of current-voltage characteristics, potentiometry and amperometry as basic measurement techniques followed by data mining and analysis. The integrated resin particles can also be imaged under microscope at different experimental conditions. These studies can provide information on fundamental processes taking place on either side of the particles and contribute to the understanding of more complex systems that contain fine resin particles randomly distributed in polymeric binder. The systems with multiple ion exchange particles create a bridge between single resin particle systems and heterogeneous membranes and the experimental studies are focused on elucidation of the effect of geometrical parameters on the overall behavior. The ultimate goal of the current project is to describe changes in the behavior of the ion-exchange systems caused by their geometrical and material heterogeneity.
