摘　　要：制备出紫茎泽兰活性炭,采用SEM对其结构与形貌进行表征。考察了该活性炭附剂对Pb2+离子的吸附性能。并探讨了紫茎泽兰活性炭对Pb2+的吸附机理,获得了相关热力学参数,表明紫茎泽兰活性炭对Pb2+去除效果良好,是一种很有应用前景的水处理剂。The activated carbon was prepared from crofton weed,whose structure and morphology were characterized by SEM. The adsorption mechanism of Pb2 +on activated carbon was studied. The related thermodynamic parameters were obtained. It was showed that the activated carbon prepared from crofton weed was a new type adsorption material with excellent application prospect.
