This study focuses on capacitive deionization (CDI) technology for rare-earth wastewater treatment, presenting an integrated chemistry experiment involving the fabrication of FeOOH@SSC self-supported electrodes through electrodeposition. The experiment encompasses material characterization, electrochemical performance testing, and CDI adsorption evaluation for rare-earth ions. By introducing cutting-edge CDI research into undergraduate laboratory education, this interdisciplinary experiment bridges theoretical knowledge in electrochemistry from physical chemistry with practical applications in inorganic chemistry, instrumental analysis, and materials science. The experiment not only reinforces fundamental theoretical concepts but also enhances students’ professional competencies in chemistry, contributing significantly to the cultivation of top-tier undergraduates capable of addressing national strategic needs and regional economic development priorities.
