混合吸附剂在环境监测中分析苯系物的性能考察

Application of Mixed Absorbents to Analyzing BTEX in Environment

摘要: 探讨了单一吸附剂和混合吸附剂对大气中苯系物的回收率,同时对比了一些洗液,发现用二氯甲烷代替二硫化碳可取得更好的结果,因为前者不仅回收率高于后者,且更有利于减少环境污染.

Abstract: The recovery rate of BTEX in atmosphere absorbed by single absorbents and multisorbent is discussed and the different shower solutions is compared. The results showed that the better recovery and lower pollution can get when CH₂Cl₂ is used as shower solution instead of CS₂.
