甲醛的共存对靛酚蓝分光光度法测定室内空气氨含量的影响研究

Research on the Impact of Formaldehyde’s Presence on the Indophenol Blue Spectrophotometric Determination of Ammonia Level in the Indoor Air

在对室内空气氨气的采样过程中不可避免地会将室内空气中共存的甲醛引入到氨吸收液中,考察了不同浓度甲醛的共存对使用靛酚蓝法测定室内空气氨含量的影响情况,分析了影响产生的原因,提出了相应的建议,可供从事室内环境检测的工作人员参考。

It is inevitable that formaldehyde will be absorbed into the ammonia sampling liquid during the sampling of ammonia in indoor.This paper investigated how the coexistence of formaldehyde with different concentrations impacts the indophenol blue spectrophotometric determination of ammonia level in the indoor air.
