室内空气环境中微(痕)量甲醛的主要分析方法

The Major Determinating Methods of Trace Formaldehyde in Indoor Air Environment

综合评述了目前国内外关于室内空气环境中微 (痕 )量甲醛的来源、危害和几种主要采样、分析方法以及最新发展的分析检测技术 ,比较了各类分析方法的优缺点并提出了今后的发展方向 .

A review with sixty-two references is given on the sources of the formaldehyde in indoor air environment and the harm to human body, introducing some methods, including active sample method?passive sampling method?adsorption method and liquid drop method, which are generally used at home and aboard. The principles and the characteristics of the spectroscopic method? HPLC method? electrochemical method? fluorescence method and other methods are commented. In this article some quick and simple analysis methods such as MBTH method with its development?HPLC-UV method?fluorescence method? Oscillometric polarogrphy method and Chemiluminescence method which have high sensitivity are emphatically mentioned. Their advantages and disadvantage are compared, and the direction of the development is pointed out in future.
