不同种类粉煤灰的XPS分析
|
摘要
选取3种粉煤灰制备成3种不同的样品,进行脱硝实验。采用X射线光电子能谱(XPS)仪检测分析这3个样品中主要元素及其化合态的结合能。结果表明:通过脱硝实验得出样品3的脱硝效果最好;通过XPS测得3种样品的主要元素均为Si、Ca、O、C、Al,但是3种样品中化合态物质不同,这是脱硝效果不同的主要原因;研究发现Ca元素的化合物种类和含量对脱硝起到主要的作用。
Three different samples were prepared from three kinds of fly ash and the denitration experiment was carried out. X-ray photoelectron spectroscopy(XPS) was used to detect and analyze the binding energy of the main elements and their chemical states in the three samples. The result is as follows: by the denitration experiment,it is found that the denitration effect of sample 3 is the best; the main elements of the three samples measured by XPS are Si, Ca, O, C and Al. However,three kinds of samples have different chemical compounds,which is the main reason for the different denitration effects; the study found that the type and amount of compounds containing Ca played a major role in denitration.
