摘　　要：主要总结了室内空气中甲醛的危害及来源,介绍了两种室内空气中甲醛含量测定方法,即酚试剂分光光度法和4-氨基-3-联氮-巯基-1,2,4-三氮杂茂(AHMT)分光光度法。对两种测定方法的线性关系、准确度、精密度、灵敏度、加标回收率做了对比,同时对两种测定法方实验过程中遇到的一些问题做了探讨和分析。This article introduces the harm and source of formaldehyde in indoor air,Two methods for determination of formaldehyde content in indoor air,namely phenol reagent spectrophotometry and AHMT spectrophotometry,are introduced too.The linear relation,accuracy,precision,sensitivity and standard recovery of the two methods were compared.At the same time,some problems encountered in the experiment of the two methods are discussed.
