甲醛检测方法研究进展

Research Progress in Analysis Methods for Formaldehyde

现有甲醛检测方法有分光光度法(包括乙酰丙酮法、酚试剂法、AHMT法、品红-亚硫酸法、变色酸法、间苯三酚法等)和电化学法(包括示波极谱测定法和电位法、气相色谱法、液相色谱法、甲醛传感器等),分析比较了现有检测方法的优缺点,提出建立简便、快速、灵敏的甲醛在线检测方法将成为今后对甲醛检测方法的研究热点.

Different analytical methods are currently used, such as Spectrophotometric including acetylacetone, 3-methyl-2-benzothiazolinone hydrazone hydrochloride-monohydrate （MBTH）, 4-amino-3-hydrazine- 5-mercapto-1, 2, 4-triazole （AHMT）, sulfurous acid-magenta, chromotropic acid and phloroglucinol method） and Electrochemical Detection containing oscilloscopic method and polarographic method, Gas Chromatogram method and High Performance Liquid Chromatogram method, Sensor detection and so on. This paper compares the advantages and disadvantages of the two methods, puts forward that it will become the hot research subject for Formaldehyde detection to establish on-line convenient, rapid, and sensitive Formaldehyde detecting methods.
