摘　　要：将活性炭纤维毡进行表面预处理后对其进行表征,并采用电感耦合等离子体光谱仪和紫外可见分光光度计在优化实验条件下,研究了活性炭纤维毡对六价铬(Cr6+)的吸附。结果表明,活性炭纤维毡对Cr6+的吸附过程符合二级动力学方程,是一种以物理-化学作用为主的吸附过程;吸附模型符合Langmuir吸附等温方程。使用活性炭纤维毡处理含Cr6+废水效果好,操作简单。活性炭纤维毡可以作为去除水中Cr6+的吸附剂。We characterized activated carbon fiber felt after surface pretreatment,and studied the adsorption of activated carbon fiber felt for hexavalent chromium(Cr^6+)by inductively coupled plasma spectrometer and ultraviolet and visible spectrophotometer under the optimum conditions.The results show that the adsorption process that the activated carbon fiber felt adsorbs Cr^6+fits the second order kinetic equation,which is an adsorption process with physical and chemical reactions.The isothermal model that the activated carbon fiber felt adsorbs Cr^6+fits the Langmuir adsorption isothermal equation.The treatment of Cr^6+containing wastewater by activated carbon fiber felt is effective and simple to operate,showing that the activated carbon fiber felt can be used as an adsorbent for the removal of Cr^6+in water.
