酚泄漏应急演练中分析方法的优化探讨

Discussion on the Optimization of Analytical Methods in Phenol Divulging Emergency Drilling

在应急监测中,分析方法的选择将影响分析数据质量和上报速度。因为酚类分为挥发酚和不挥发酚,挥发酚是指在磷酸和硫酸铜的存在下,在pH=4加热蒸馏时随蒸汽挥发出来的酚类物质。蒸馏太多样品及采用不合适的分析方法都会耗费大量时间,对酚应急监测工作不利。文章通过实验验证的方式,提出了在应急监测演练中正确选择酚分析方法、提高分析速度的一些建议。

In environmental emergencies monitoring,the choices of analytical method will affect analysis data quality and reporting speed.phenols is divided into non-volatile phenol and volatile phenol,and volatile phenol refers to these compounds which would evaporate with steam when heated on pH=4 under the existence of phosphoric acid and copper sulfate.Distillation of too many waste water and the use of inappropriate analysis method would be time-consuming and not conductive to volatile phenol emergency monitoring.Because of that,the paper proposed some recommendations to help make the correct choice for phenol analysis to improve the analytical speed during the emergency monitor drilling through series of experimental test.
