黑碳的表面化学研究进展

Advance of Research on Surface Chemistry of Black Carbon

黑碳是生物有机体或化石燃料不完全燃烧形成的一种含芳香环的高聚产物,环境中黑碳的存在将对有机污染物产生较强的吸附作用。最新的研究表明:黑碳的表面基团和表面化学性质将极大影响其对污染物的吸附行为。以近来的活性炭表面化学的研究为参照,综述了黑碳及活性炭的表面化学的研究进展,讨论了碳表面化学与吸附性质之间的联系,进一步探讨了黑碳作工业用吸附剂的可能性。

Black carbon is one of the ubiquitous impure materials produced by incomplete combustion of biomass or fossil fuel. The existance of black carbon will result in adsorption on organic compounds. Recent findings have revealed that the adsorption behavior to contamination will be affected seriously by the surface groups and chemistry properties of black carbon. In this paper, referring to recent studies of surface chemistry of activated carbons, the authors summarized comparatively the advance of research on surface chemistry of black carbon and activated carbons, discussed relations between surface chemistry and sorption properties of carbon, and further probed into the possibilities of black carbon sorbent applied in industry.
