摘要
伴随着人类生活水平的不断提高,一些具有挥发性有机物污染也日趋严重。甲醛是一种常见的空气污染物,已经被世界卫生组织确定为致癌和致畸的物质, 对它科学有效处理也受到了社会各界的普遍关注。如何建立高效的室内空气中甲醛的净化方法一直是改善室内空气品质的最新课题。目前在解决挥发性室内有机污染物的方法之外,要更好的解决室内污染问题还需要人们的不断努力取研究。
本文着重概述了甲醛的性质,来源,毒性以及对人体的危害,综述了现有甲醛的检测方法有分光光度法(乙酰丙酮法,变色酸CTA分光光度法)和电化学法等。以及各种方法的优缺点。提出了建立简便,快速,灵敏的甲醛检测与治理方法。

ABSTRACT
With the human life level unceasing enhancement, some volatile organic matter pollution is serious. Formaldehyde is a common air pollutants has been confirmed by the world health organization (who) as the substances that cause cancer and birth defects, scientific and effective treatment for it also received widespread attention from all walks of life. How to establish efficient of the formaldehyde in indoor air purification method improved indoor air quality has been the latest issue. Indoor volatile organic pollutants in the existing processing method, on the basis of people constantly seeking a better air purification technology in order to better solve the problem of indoor pollution.
An overview of the formaldehyde properties, sources, toxicity and harm to the human body, summarizes the existing detection methods of formaldehyde spectrophotometry (acetyl acetone method, CTA acid spectrophotometry) and electrochemical method. The advantages and disadvantages of various methods. Put forward to establish a simple and rapid and sensitive methods for detection of formaldehyde will be the focus of future research.
