摘　　要：采用微波辅助合成法制备有机膨润土,以十六烷基三甲基溴化铵为改性剂,针对微波改性有机膨润土制备过程中的关键因素对苯、甲苯及二甲苯吸附性能的影响进行研究。表明微波合成有机膨润土最佳条件为微波辐照反应时间3min、改性剂用量120mmol/100g、微波功率320W及固液比1:8。有机膨润土对苯系物的吸附量大小依次为二甲苯>甲苯>苯,有机膨润土含碳量大小与苯系物的吸附能力具有明显的正相关性。The organobentonite was prepared using microwave with hexadecyltrimethyl ammonium bromide （HTAB） as modified agent. The effects of organobentonites preparation key factors of using microwave on their adsorption properties for benzene/toluene/xylene were investigated. The organobentonite preparation optimal conditions using microwave were that addition amount of HTAB was 120 mmol/100g of sodium bentonite, the microwave reaction time was for 3min, microwave power was 320W and the ratio of solid to liquid was 1：8. The adsorption capacity order of organobentonites for benzene/toluene/xylene was xylene〉 toluene〉 benzene at the same conditions. The sorption capacity of organobentonite was positively correlated with its organic carbon contents.
