2、受关注,吸附回收治理技术作为污染治理及溶剂回收的有效手段,仍是当前研发热点,而探索简易、低能耗、易推广的测试手段和方法,对吸附材料做出吸附、再生性能评价,有利于工业应用及室内空气净化的推广。基于简易、低能耗、易推广的测试原则,自制玻璃吸附管,手动过管吸附、热解吸脱附,结合热解吸与气相色谱分析方法,就黏胶基活性炭纤维(VACF)与颗粒状椰壳活性炭(GAC)对三苯混合共存条件下三苯吸附及120脱附再生性能比较测试,由常温吸附性测试发现,VACF用量少,其对三苯吸附力明显优于GAC;由120恒温、氮气吹扫流速50mLmin脱附比较发现,VACF对苯
3、与甲苯脱附力强,而对二甲苯脱附力却低于GAC。关键词:黏胶基活性炭纤维(VACF);颗粒状椰壳活性炭(GAC);吸附率;脱附率中图分类号:X701文献标识码:ADOI:103969.jissn.1674-991X.201102027ComparisonoftheAbsorptionandDesorptionCharactersofActivatedCarbonFiberandGranularActivatedCarbononBenzene,TolueneandXyleneMixedGas11211ZHANGZhihong,CH
