摘要
本文研究了气相色谱测定空气中苯含量方法,用活性炭吸附,二硫化碳洗脱。本方法灵敏度高,选择性好,适用于检测工业废气中多种污染物共存时的苯含量,当采样体积为100升时,可检测空气中0.001mg/m^3的苯。
This is an article about determing the content of the C6H6 in air by gas chromatography.cleaning CS2 by the adsorption of activated carbon.The means is provided the higher sensitivity, the better selectivty.It is applicable to determine the content of the coexisted C6H6 and waste in the industry fume. When the volume of the sampling achieves 100L, We can measure the 0.00lmg/m3 C6H6 in air
