商品甲醛去除剂除醛性能研究
The performance of commercial formaldehyde removers for formaldehyde in air
摘要
Abstract
Housing decoration can cause formaldehyde pollution in indoor air,which endangers human health. In order to acquire the effect of commercially available formaldehyde removers, four photocatalytic and enzyme formaldehyde removers are chosen to investigate the performance of commercial removers for formaldehyde in this paper. The removal effect of formaldehyde for the liquid and dry remover samples sprayed on the polyester supporter are tested and compared on the self-built experimental device.The production of carbon dioxide in the process of the formaldehyde removal is also tested. Furthermore,the mechanism of removing formaldehyde for the selected commercial removers is explored. The results showed that the liquid remover samples sprayed on the supporter exhibite good removal effect for formaldehyde(83%~92%),while the performance of the formaldehyde removal for the dry remover samples on the supporter reduce significantly.And the formaldehyde is not found to convert into carbon dioxide.The physical adsorption of the formaldehyde in water plays a critical role in the removal of the formaldehyde.关键词
