摘要
目的对比酚试剂法与快速仪器法在检测室内空气中甲醛浓度的结果差异,验证快速仪器法的实用性。方法分别采用酚试剂法与快速仪器法对室内空气中不同浓度甲醛进行检测,结果进行统计学分析。结果检测结果经统计学分析,t<t0.05(5),P>0.05,快速仪器法与国标酚试剂法两种方法检测结果差别无显著意义。结论快速仪器法可满足现场快速检测需要。
Objective Comparing the result of formaldehyde concentration detected by rapid instrumental method and MBTH spectrophotometric method, testing the effectiveness of rapid instrumental method. Methods Detecting various concentration of formaldehyde in indoor air by rapid instrumental method and MBTH spectrophotometric method, analysing the result by statistical method. Results Two method of determination of formaldehyde in indoor air have no Statistical differences. Conclusions Rapid instrumental method is suitable for the spot detecting.
