摘要
本文用化学、仪器两种方法对居室空气中的甲醛进行了样品的对照实验及显著性差异的检验,并对化学法标准曲线进行了回归方程检验。结果表明:标准曲线符合要求;两种方法所测样品结果无显著性差异,且用甲醛检测仪省时省力,是开展室内甲醛监测的理想仪器之一。
We used two ways to monitor the content of formaldehyde in indoor air. One was chemical analysis, the other was instrumental analysis. We took the control test and the test of significance between them. It was the result that the standard curuse accorded with reguire, the two ways had not significant difference, and clearly, the instrumental way was easy to operate and took less time.
