| Abstract: | The chemical states of sulfur in particulate emissions from domestic stoves and power stations were determined by X-ray photoelectron spectro-scopy(ESCA).Four separatechem ical species of sulfur were identified, namely, SO3, SO4-,SO2 and SO3-. Effects of combustion conditions on the chemical states of sulfur are discussed. |
