气相色谱法同时测定地表水中丙酮和丁酮

摘要

By purge and trap gas chromatography method for the determination of acetone and butanone in surface water, the purge and trap conditions were optimized. The method has the advantages of high sensitivity, accuracy, simple operation and other characteristics, acetone. The detection limit is 0.08 μ g/L, the detection limit is 0.10 μ g/L butanone, suitable for the determination of surface water and drinking water, acetone and butanon.%采用吹扫捕集一气相色谱法测定地表水中丙酮和丁酮，并对吹扫捕集的条件进行优化。该方法具有灵敏度高、定量准确、操作简便等特点，丙酮的检出限为0.08μg/L、丁酮的检出限为0.10μg/L，适合于地表水和生活饮用水中丙酮和丁酮的测定。
