摘　　要：以废弃的大孔吸附树脂为原料制备炭化树脂，研究了炭化树脂吸附去除有毒有机物二氯甲烷的效果，并和水处理中常用的活性炭JW-208进行了对照，2种吸附剂对二氯甲烷的吸附等温线符合Freundlich方程．在．实验浓度和温度范围内，炭化树脂对水中二氯甲烷的静态吸附能力优于活性炭JW-208的吸附能力（前者是后者的1．7～2．7倍），其吸附处理量和吸附处理效果都优于活性炭．Based on envirmental protection and economy, carbonaceous adsorbent with abundant micro- pore used to remove dichloromethane in aquaeous solution were prepared by carbonizing waste macro- porous adsorption resin aiming at ＂controling waste with waste＂. Compared with those of active car- bon JW-208, the adsorption for removing dichloromethane in aquaeous solution was studied with car- bonaceous adsorbents. The adsorption isothems of dichloromethane onto two adsorbents were fitted into Freundlich equation. In this experiment, the adsorption capacity of dichloromethane on carbona- ceous adsorbents was better than that on JW-208, in which the former was 1.7 - 2.7 times of the lat- ter.
