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。
Abstract：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 p H value of medium, were investigated. When the initial concentration of hexestrol was 2mg/L, the adsorption with nylon 6 nanofibrous membranes obeyed the Pseudo-first-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.
