| 摘 要： | 建立了废水中甲醇的3种分析方法，毛细管柱气相色谱法、填充柱气相色谱法和变色酸分光光度法。测定废水中甲醇浓度相对标准偏差分别为1．45％，2．93％，3．61％，平均回收率分别为100．88％，98．19％，97．62％。实验结果表明：3种方法能较好对应，其中毛细管柱气相色谱法灵敏度最高，方法检出限为0．05mg／L。

| Abstract: | Three analytical methods,capillary gas chromatography,packed column gas chromatography and chromotropic acid spectrophotometry,were developed for the determination of methanol in wastewater.The three methods were successfully used in the determination of methanol in wastewater.The relative standard deviations are 1.45%,2.93% and 3.61%,and the average recovery rates are 100.88%,98.19% and 97.62%,respectively.The results indicate that:The three methods correspond well;The sensitivityof the capillary gas chrom... |
