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 de...
Pyrrole-Based Extraction Materials for Microcystin Separation and Analysis
Project ID: D2018-20Background When water conditions are favorable for cyanobacteria growth, harmful algae blooms (HAB) can result, causing elevated levels of toxins called microcystins (MCs). There are over 140 microcystin variants. The EPA suggests that MC-LR variant concentration in drinking water should be less than 0.3 ug/L. Trace levels of M...
