甲醛测定方法的研究进展

Research Process for Formaldehyde Determination Methods

甲醛是一种重要的工业原料,在化工、食品、建材等方面有着广泛的应用。由于甲醛毒性大,且具有致癌作用,目前已被认为是工厂区和室内空气中最重要的污染物之一。随着人们对空气污染的日益关注,对甲醛的准确及时检测显得更加重要。本文综述了几种常用的甲醛测定方法,包括分光光度法、色谱法和甲醛传感器,并对每一种方法的应用情况作了简要的评述。

Formaldehyde was an important industrial raw materia1 and was used extensively in chemical, food and building materials. Owing to its high toxicity and possible carcinogenic properties, formaldehyde was recognized as one of the most important pollutants in both workplace and ambient atmosphere. Along with people’s increasing attentions on air pollution, accurate and rapid determination method for formaldehyde was even more important. Several kinds of commonly determination methods of formaldehyde was reviewed in this paper, included spectrophotometry, chromatography and formaldehyde sensor. The application of each method was briefly presented.
