Removal and Recovery of Rare Earth Elements

Project ID: D2022-17 Rare earth elements (REEs) are critical inputs for advanced technologies including permanent magnets, electronics, clean energy systems, fiber optics, and defense applications. Elements such as neodymium, europium, dysprosium, terbium, and yttrium are particularly important due to their unique magnetic, optical, and catalytic...

Novel Class of Materials for Boron Extraction

Project ID: D2009-11 Background Solid Phase Microextraction (SPME) has gained widespread acceptance and use in laboratories due to the fact that it is a solvent-less extraction technique, its mode of operation is relatively simple, easy to automate, and sampling and sample preparation are combined into one step. Until now, methods that coat SPME...

Pyrrole-Based Composites for Metal Extraction and Analysis

Project ID#: D2018-57Invention DescriptionThe researchers at the University of Toledo have developed a chelating polypyrrole powder that can be used for filtration by directly mixing with samples and passing the sample through a filter. Desorption is then accomplished by simply dropping the pH. Applications• Selective microextraction devices•...
