Discussion on Determination of Formaldehyde in Indoor Air by the Spectrophotometric Method

According to the characteristics of formaldehyde in indoor air, traditional acetylacetone spectrophotometric method was optimized in the aspects of sampling, sample collection, sample flow and so on; the optimized air quality determination method improved indoor air monitoring accuracy, had simple and fast characteristics. In this paper, indoor air formaldehyde content of 12 residences in a city were detected, indoor air formaldehyde content of 8 residences was over the national indoor air quality standard GB/T18883-2002.
