Quantifying Trace Elements in Coal Applications with XRF

Trace Elements. Like any other geological material, coal often contains trace elements like cadmium, chromium, nickel, beryllium, molybdenum, zinc, copper, antimony, lead, cobalt, manganese, vanadium, and arsenic. Some of these trace elements are air pollutants or otherwise considered to be hazardous. Coal ash also retains these trace elements.
