摘要
[目的 ]探讨新装修居室空气中甲醛污染的持续时间、主要污染来源及控制方法。 [方法 ]采用酚试剂分光光度法测定甲醛浓度。[结果 ]新装修的居室关闭门窗 4h后空气中甲醛的浓度趋于稳定 ;装修后 5个月的过程中 ,甲醛浓度逐渐降低。室内甲醛主要来源于装修和装饰材料 ,但双面贴橱柜中甲醛浓度比单面贴的橱柜低得多 ,铺实木地板的房间甲醛浓度比铺金钢板的低 ,涂环保漆的房间中甲醛浓度比涂非环保漆的房间低。[结论 ]要控制甲醛污染 ,首先应使用环保型安全无毒或低毒的建筑装潢材料 ,装修后充分通风 ,并采用空气净化方法 。
To study the pollution duration, sources and the method of formaldehyde control in indoor air of newly decorated room \ Formaldehyde concentration (FC) was detected by spectrophotometer with phenol reagent \ FC in the air was tended to a stable levels after closing the windows 4 hours FC decreased gradually during the 5 months after decoration The pollution of Formaldehyde were mostly from the decoration materials FC in double faced cabinet was lower than that in single face FC in the room with xylary floor was lower than that with wood based panels FC in the room painted with environmental protection lacquer was lower than that with common lacquer \ It is important for using low or non toxic materials for decoration and ventilating fully to decrease room pollution by formaldehyde
