摘　　要：采用静电纺丝设备制备尼龙6纳米纤维膜。用静、动态吸附方法,研究了尼龙6纳米纤维膜对己烷雌酚的吸附性能,考察了吸附时间、初始浓度及介质p H值对尼龙6纳米纤维膜吸附己烷雌酚的影响。结果表明,初始浓度为2mg/L时,尼龙6纳米纤维膜吸附己烷雌酚的过程符合准一级动力学模型;当初始浓度在5~20mg/L范围内,吸附过程符合准二级动力学模型。尼龙6纳米纤维膜吸附己烷雌酚的过程符合Freundlich等温吸附模型。Nanofibrous membranes of Nylon 6 were prepared by electrospinning. The adsorption properties of nylon 6 nanofibrous membranes for hexestrol were studied by static and dynamic adsorption method. The influencing factors, such as adsorption time, initial concentration of hexestrol and pH value of medium, were investigated. When the initial concentration of hexestrol was 2mg/L, the adsorption with nylon 6 nanofibrous membranes obeyed the Pseudo-ftrst-order kinetic model; and when the initial concentration was in the range of 5-20mg/L, the adsorption accorded with the Pseudo-second-order kinetic model. The adsorption of hexestrol with nylon 6 nanofibrous membrane agreed with Freundlich isothermal adsorption model.
