三氯甲烷又名氯仿(CHCl_3),无色透明易挥发液体,工业上大量用作溶剂。空气中三氯甲烷在光的作用下能被氧化成氯化氢和光气,毒性较大。目前国外已列为可疑致癌物质。为此我们作了用固体吸附剂采样测定空气中三氯甲烷方法的研究。色谱法常用大注射器采样,最大的缺点是不易保存,由于吸附、泄漏等问题造成分 Trichloromethane, also known as chloroform (CHCl_3), colorless and transparent volatile liquid, a large number of industrial solvents. Trichloromethane in the air under the action of light can be oxidized to hydrogen chloride and phosgene, greater toxicity. At present, foreign countries have been classified as suspected carcinogens. To this end we made a solid adsorbent sampling determination of chloroform in the air method. Chromatography commonly used large syringe sampling, the biggest drawback is not easy to save, due to adsorption, leakage and other issues caused by points
