Removal and Recovery of Rare Earth Elements

Project ID: D2022-17 Background Rare earth elements (REEs), such as neodymium, europium, dysprosium, terbium, and yttrium, are sometimes referred to as the “vitamins of modern industry” due to their frequent use in high-tech applications. They are used in fiber optics to carry internet traffic, making gasoline from petroleum, and in items...

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•...
