摘　　要：微型环境化学实验是一种用微型化的仪器、装置和极少量的试剂来做环境化学实验的方法。微型环境化学实验是近年来迅速发展起来的实验方法,具有现象明显、试剂少、效果良好、节省经费和时间、污染低、安全等优点,受到化学工作者的青睐,同时是"绿色化学"的体现。甲醛是室内空气中常见的有机污染物。室内空气中的甲醛污染大多是来自于装修,被称为室内隐形杀手的甲醛,是室内环境污染最大的来源之一,对居民的身体健康造成巨大的威胁和伤害。因此,本文对室内空气中的甲醛进行检测分析,实验证实微型实验比常规实验时间少、试剂少。我们用微型实验设备进行实验更为方便、准确。Microscale experiment of Environmental Chemistry is a measure to do experiments with tiny instruments, devices and a low dose of reagents. It is favored by a number of chemical workers because of its following reasons such as obvious phenomenon, a low dose of reagents, favorable effects, little cost, time - saving, little pollution, and safety. Meanwhile, it is a picture of green chemistry. Methane is one of the most common organic pollutant found in indoor air. It often comes from decoration. Lately, malignant accident case which is led by the invisible killer, methanal, has great threat also harm to residents＇ health. So it＇s crucial to detect and analyze the methanal in the air indoor. Both time and regent of Microscale experiment is less than the conventional one, and it is more convenient and accurate.
