建立了吹扫捕集-气相色谱法测定水中丙酮的方法。该方法聚具有灵敏度高、检出限低、定量准确、操作简便等特点。当进样量为5ml时,检出限为0．1μg/L,加标回收率在94．5%-103．6%之间,测定结果的相对标准偏差均小于3%。
건립료취소포집-기상색보법측정수중병동적방법。해방법취구유령민도고、검출한저、정량준학、조작간편등특점。당진양량위5ml시,검출한위0．1μg/L,가표회수솔재94．5%-103．6%지간,측정결과적상대표준편차균소우3%。
We establish a method to determine acetone in water with purge and trap- gas chromatography. The method has high sensitivity, low detection limit, high accuracy and simple operation step. When the sam-ple size is 5ml, the detection limit is 0. 1μg/L, the recovery rate is 94. 5% -103. 6% and the relative stand-ard deviation is less than 3%.
