甲醛（HCHO）是一种主要的室内空气污染物。作者开发了一种敏感的扩散采样器气体HCHO在空气中ppb水平暴露30分钟。通过小室实验确定了采样器的吸收率，并根据Langmuir理论建立了动态吸附模型。现场试验证明该采样器在生活环境中使用成功。
Formaldehyde (HCHO) is a major indoor air pollutant. Authors have developed a sensitive diffusion sampler of gaseous HCHO in air at ppb level for 30min exposure. An uptake rate of the sampler was determined by a small chamber experiment and theoretically evaluated by a dynamic sorption model based on Langmuir theory. Field tests proved successful use of the sampler in living environment.
