摘要
室内空气污染正威胁着人类的身体健康,而甲醛是室内主要污染物之一。借助傅立叶变换红外光谱、X射线光电子能谱和热重分析对二氧化锰脱除甲醛前后进行了表征。通过对表征结果的比较可知,在脱除甲醛过程中,二氧化锰起了催化氧化作用,能将甲醛氧化成二氧化碳和水,也能使甲醛缩聚生成多聚甲醛。
We are all threatened by the pollution of indoor air. Formaldehyde is one of the main indoor pollutants, some characterization technologies such as Fourier transform infrared spectrum, X-ray photoelectron spectra, and thermogravimetrie were used for the analysis of manganese dioxide. The results showed that in the process of formaldehyde adsorption, formaldehyde could be oxidized into carbon dioxide and water or turned into polyformaldehyde by using manganese dioxide.
