Scientists from the University of Chicago and Argonne National Laboratory have modified the molecular surface of capacitive deionization (CDI) electrodes, which could efficiently remove metal ions from water, as per information from the source. CDI is a promising technology for filtering unwanted minerals and metals from water and preserving the elements for reuse elsewhere.
The researchers investigated the best way to alter these surfaces and found functional group modifications on the electrode’s surface, allowing the device to selectively adsorb different types of ions from water. The team used experimentation, machine learning, and high-energy X-rays to develop a more efficient CDI device that could remove lead much more efficiently than before.
The technology’s development could have far-reaching implications in removing toxic metals from drinking water, preserving other minerals for reuse, and driving the recovery of resources important in clean energy applications to move toward a circular economy.
The UChicago-Argonne team’s project benefited from seed funding from the UChicago Joint Task Force Initiative, which fosters collaboration between these institutions to achieve mission success.
