New Sensor Able To Detect Rare Earths In Acid M... -

For decades, the abandoned coal mines of Appalachia have bled "orange water"—a toxic cocktail known as acid mine drainage (AMD) that chokes local streams and rivers. But recent breakthroughs are transforming this environmental burden into a high-tech gold mine. The Problem: A Toxic Legacy

: It works in highly acidic environments and is as accurate as the "gold standard" laboratory mass spectrometry (ICP-MS), but is potentially portable and far cheaper. Impact: Turning Waste Into Wealth New sensor able to detect rare earths in acid m...

: When the protein binds to a specific element like terbium , it glows green under UV light. For decades, the abandoned coal mines of Appalachia
