为解决目前抗生素与重金属复合污染问题，采用紫根水葫芦基活性炭（Long-root Eichhornia crassipes-activated carbon，LREC-AC）吸附水溶液中的氧氟沙星（Ofloxacin，OFL）和Cu2+，并对其吸附特性和机理等进行研究。结果表明，LREC-AC对OFL和Cu2+的吸附均符合Langmuir模型及拟二级动力学方程。LREC-AC对OFL的吸附机理包括电子供体-受体相互作用、氢键作用和静电引力作用，而对Cu2+的吸附机理则包括静电引力作用，以及电子交换或共价键等作用。在此基础上，考察OFL-Cu2+复合体系中LREC-AC对OFL和Cu2+吸附特性和机理。在复合体系中，LREC-AC对OFL和Cu2+的饱和吸附量分别为59.34 mg·g-1和3...
