GFAAS provides insights into trace element (TE) sulfides speciation during coal combustion.

TGA-DSC was used under varied N₂ flow rates to study microaerobic regimes of TE evolution.

Antimony trisulfide demonstrated strong binding affinity to the carbon surface.

Selenium disulfide tends to form molecular clusters prior to vaporization.

TE sulfide evaporation is the rate limiting step.
