The study focuses on the potential of removing toxifying Pb from a certified, multi‐element fly ash (BCR176) by thermal treatment between 300 and 950 °C under different carrier gas compositions (Ar or Ar + O 2 ). The treatment was studied by in situ monitoring the evaporation rate of Pb, C, S, Na, and K during heating and by synchrotron X‐ray absorption spectroscopy of selected samples collected during vaporization at the Pb L 3 ‐edge.
