A staple of chemistry classroom demonstrations may offer a solution for cleaning up decades’ worth of toxic solvents polluting the environment, new research suggests.
Potassium permanganate is a disinfectant used by water treatment plants, and is sometimes also used to treat pollution stemming from industrial-grade solvents that were buried 30 to 40 years ago.
"But most people who use potassium permanganate to treat pollution pump it into a well in liquid form every day for a couple of months," said Frank Schwartz, a study co-author and a professor of geological sciences at Ohio State University. Like salt, potassium permanganate is granular and dissolves when it comes into contact with water.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
