Abstract: The article mainly takes sulfur dioxide in the air as the basic research object,collects samples from the air by passive absorption sampling method,and combines the principle of ion chromatography to explore the problem of determining sulfur dioxide in the air by ion chromatography.

Key words: passive absorption sampling;ion chromatography;sulfur dioxide

被動式吸收采样是指采用特定材质、尺寸的管,一端盛有装吸收液的网片,通过空气中待测气体分子的扩散作用来采集样品的过程。(剩余2446字)
