去除室内甲醛的技术进展

Technological Advances in the Removal of Indoor Formaldehyde

甲醛是一种会对人类健康造成严重威胁的装修材料,由于甲醛即使在低浓度下也会引起疾病和不适,所以需要减低技术。在过去几十年里,越来越多的研究者报道了去除室内甲醛的方法。这样的方法有:吸收、化学吸附、物理吸附、光催化分解、膜分离、等离子和催化氧化。这里我们回顾这些技术的性能、原理和优缺点,并对其发展趋势做出展望。

Formaldehyde is a renovation material that poses a serious threat to human health, and because formaldehyde can cause illness and discomfort even at low concentrations, abatement techniques are needed. Over the last few decades, more and more researchers have reported methods to re-move formaldehyde from indoor areas. Such methods are absorption, chemisorption, physical ad-sorption, photocatalytic decomposition, membrane separation, plasma and catalytic oxidation. Here we review the performance, principles and advantages and disadvantages of these technolo-gies and give an outlook on their development trends.
