The process of removing indium ions from aqueous solutions by applying capacitive deionization (CDI) is reported in this manuscript. First, a modified carbon material was prepared by incorporating titanium dioxide (TiO2) into activated carbon (AC). A microwave-assisted ionothermal synthesis (MAIS) method was used to produce evenly distributed nanostructured anatase TiO2 on the surface of AC. A polyurethane (PU) elastomer was then synthesized as the binder material instead of using conventional polyvinylidene fluoride (PVDF). By combining the aforementioned materials, a MAIS TiO2/AC-PU electrode was synthesized and applied to CDI tests. Scanning electron microscopy (SEM) was used to characterize the size and dispersion of the composites. For electrochemical properties, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to analyze the synthesized electrode. The performance of the prepared electrode during the CDI process was tested in different concentrations of indium solutions. It was discovered that the indium removal efficiency can be as high as 84% in 1 and 5 ppm of indium solutions.

“…128 The AC composite electrode is generally cast by a slurry mix comprised of AC, a polymer binder, and an electronically conductive additive. Polymers such as Nafion 107 and polyurethane 141 have been studied as the binder for AC composite electrodes. Nafion possesses excellent charge-selectivity, which can enhance the adhesion between AC particles (as shown in Fig.…”
