预处理方法对黄水气相色谱分析的影响

Effects of Pretreatment Methods on GC Analysis of Yellow Water

采用气相色谱法对黄水的主要成分进行分析,并对采用膜过滤、酒精沉降、蒸馏、萃取、离心等预处理方法处理的黄水样品进行分析和比较。结果表明,离心法处理后的样品在气相色谱分析时能真实反映黄水的主要组分,且省时省力,提高分析效率。

The main compositions of yellow water were analyzed by GC. Yellow water samples pretreated by different methods such as membrane filtration, alcohol settlement, distillation, extraction, centrifugation etc. were analyzed by GC and the GC analysis effects were compared. The results indicated that GC analysis of yellow wate sample by centrifugation pretreatment could truly display the main compositions of yellow water and such pretreatment could improve analytic efficiency and save analytic time.
