Implication

Spectroscopic analysis reveals distinct zinc speciation forms in municipal solid waste fly ash, highlighting critical implications for material recovery.

Key Points

Multiple zinc speciation forms occur across municipal solid waste incineration fly ash, where potassium zinc chloride salts represent key reactive compounds.
X-ray absorption spectroscopy analyzed fly ash from five full-scale boilers against a tailored spectral library comprising over 30 reference zinc compounds.
Identification of these zinc speciation states clarifies material recovery potential and unwanted leaching risks, aided by nano-xanes and sequential leaching.
