民用建筑室内空气中甲醛浓度检测方法的探讨

Discussion on Detection Method of Formaldehyde Concentration in Indoor Air of Civil Buildings

目前检测室内空气中甲醛浓度的方法主要有MBTH分光光度法和AHMT分光光度法。两种方法均有各自的优点和缺点。从检测原理、方法操作性对比;灵敏度、检出限、精密度、准确度等对比试验及引入干扰研究等多方面,探讨哪种方法更适合GB50325-2020《民用建筑工程室内环境污染控制标准》。

The main methods to detect formaldehyde concentration in indoor air are MBTH spectrophotometry and AHMT spectrophotometry at present.Both methods have their own advantages and disadvantages.The detection principle,operability,Sensitivity,detection limit,precision,accuracy,interference research and other aspects were analyzed and compared,Which method is more appropriate for GB50325-2020<Stand for indoor environmental pollution control of civil building engineering>were explored.
