摘　　要：以腈纶纤维为原料络合Fe3+制得偕胺肟合铁(Ⅲ)纤维,用其处理α-萘酚溶液,研究了偕胺肟合铁(Ⅲ)纤维对α-萘酚的吸附工艺条件和吸附动力学参数。实验结果表明,偕胺肟合铁(Ⅲ)纤维对α-萘酚的最佳吸附工艺条件为pH=3.0、吸附温度313.15K和吸附时间45min。在最佳工艺条件下,偕胺肟合铁(Ⅲ)纤维对α-萘酚的吸附在所研究的α-萘酚浓度范围内符合Freundlich等温吸附方程。未达到饱和吸附前,偕胺肟合铁(Ⅲ)纤维对α-萘酚的吸附符合一级反应动力学特征。The amidoxime-Fe(Ⅲ) fiber was made by complexation of Fe3+ on acrylic fiber(PAN),and was used to treat α-naphthol solution. The process conditions and the kinetic parameters of the adsorption of α-naphthol on amidoxime-Fe(Ⅲ) were studied. The results show that under the optimum adsorption conditions of pH 3.0,adsorption temperature 313.15 K and adsorption time 45 min,and in the researched range of α-naphthol concentration,the adsorption accords with Freundlich isotherm and the kinetics of the adsorption before saturation accords with first-order reaction.
