用X射线光电子能谱测定烟尘中硫的化学状态
- X-RAY PHOTOELECTRON SPECTROSCOPIC STUDY OF THE CHEMICAL STATES OF SULFUR IN PARTICULATE EMISSIONS FROM COAL-FIRED STOVES
- 摘要:用x射线光电子能谱(ESCA)测定了家用蜂窝煤炉烟尘及燃煤电厂飞灰上存在的硫的化学状态,鉴别有SO3、SO4-、SO2和SO3-几种不同的硫化合物,讨论了燃烧条件对硫的化学状态的影响。
- 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.
