摘　　要：选用了国内外文献报道的五种常用有机废气吸收液(矿物油、废机油、二乙基羟胺、聚乙二醇、[BMIM]PF6),采用自行设计的在线吸收装置,实验研究了比较五种吸收液对二甲苯的吸收效果。饱和吸收量、有效吸收量与去除率作为吸收液的评价指标,在相同实验条件下,二乙基羟胺对二甲苯的吸收饱和量最大,其次是矿物油、废机油、[BMIM]PF6,而聚乙二醇去除率最差。本研究结果为二甲苯废气的吸收液的选择提供理论依据。Evaluation of xylene absorption capability by five kinds of liquid ： Mineral oil, di（2-ethylexyl） adipate （DEHA）, waste lubricant oil, polyethylene 400 （PEG400）, [BMIM]PF6 was performed using a self-designed absorption device. The saturated absorption amount, effective absorption and removal of the absorbing liquid was used as the evaluation index. Under the same experimental conditions, DEHA showed the greatest xylene absorption capability, followed by mineral oil, waste lubricant oil, [BMIM]PF6 and PEG400. The result provides a theoretical basis to select a high performance absorption liquid of xylene gas.
