研究了羊毛配体与铁离子之间的配位反应，并分别采用Lagergren准一级动力学模型、准二级动力学模型以及颗粒内扩散模型对实验数据进行拟合。考察了铁离子初始浓度以及pH值等因素对羊毛铁配合物催化性能的影响。使用紫外可见吸收光谱和液相色谱分别探讨了活性红195的光催化氧化降解过程。研究结果表明，羊毛与铁离子之间的反应更符合准二级动力学方程，以化学反应为主，在较高铁离子浓度下制备得到的羊毛铁配合物在pH≤6的水溶液中对活性红195具有较高的催化性能。

The coordination reaction between wool fiber and Fe3+ were carried out .The Lagergren first-order equation ,the pseudo second-order equation and the intra-particle diffusion models were employed to fit the experimental data .Then the effect of initial concentration of F e3+ and pH values on catalytic performance was investigated .The photocatalytic oxidation process of Reactive Red 195 was discussed by the UV-Vis spectra and HPLC techniques .The results indicated that the reaction process between wool fiber and Fe3+can be well described by the pseudo second-order equation .The higher catalytic activity of wool-Fe complexes prepared with higher Fe3+ concentration was obtained in the solution with pH ≤6.0 .
