） 摘要： 甲醛是一种造成室内空气污染的主要的有害气体
本文建立在气相色谱法检测室内空气中甲醛方法的基础上
我国室内空气质量标准规定
对采集空气中的甲醛进行快速气象色谱测定
以纳米铁氧体为固定相填充气相色谱柱

） Abstract： Formaldehyde is one of the most important industrial materials, but indoor formaldehyde contamination is seriously harmful to the human health
Our national criterion of indoor-air quality prescribes that the maxima limit concentration of formaldehyde is allowed 0
08 mg/m3
We constructed a new rapid method by gas chromatography(GC) with columns packed with nano-ferrite to determine the indoor formaldehyde
Results showed that it was at about 2
30 min to emerge formaldehyde\\\\\\\\\\\\\\\'s well chromatograph peak
The relative standard deviation was 2
3%~ 4
8% and the recovery rate and the correlation coefficient could reach 93
5%~108
3% and 0
9975, respectively
