摘要
采用毛细管气相色谱内标法测定苯酚中的有机杂质,通过用不同极性的两根毛细管柱作比较,不同的分析要求可以采用不同的毛细管柱,对苯酚的生产和用户的质量控制具有一定的指导作用,为制定企业标准苯酚中有机杂质指标提供一定的理论依据。
The organic impurities in phenol was determined with gas chromatography internal standard method. Two kinds of capillary columns with different polarity were compared, suitable capillary column can be used according to the requirements of analysis. The result has some guidance to producer and user of phenol and a theoretical basis for enterprise standards established of organic impurities indicators in phenol.
