A control system for operating and investigating reactors: The demonstration of parasitic reactions in the water desalination by capacitive de-ionization

► Design and assembly via LabVIEW software of an elaborate experimental CDI system. ► The interpretation of residual current and pH fluctuations upon voltage cycling. ► XPS indications for the formation of surface oxide groups by the CDI Process. ► Controlling the surface reactions by reducing the working voltages. ► Controlling the surface reactions by varying the gaseous environment.
