摘要
提出了工业冰乙酸中微量丙酸气相色谱法测定的分析方法。采用PEG20M石英毛细管分离乙酸中的丙酸,以外标法进行定量。方法的相对标准偏差RSD为2.75%,加标平均回收率达99%。
The thesis proposes a trace propionic acid of industrial ice acetic by gas chromatography was developed for the determination method of analysis.Adopt PEG20M quartz capillary separation of propionic acid,acetic acid beyond standard method for quantitative.Methods relative standard deviation RSD 2.75 %,the average recoveries were 99 %.
