摘　　要：在皮革的生产加工过程中,角蛋白未能得到充分利用便被处置,造成了一定的资源浪费。通过溶液共混法制备了角蛋白/酚磺酸缩合物复合材料,并考察其对亚甲基蓝的吸附性能。研究结果表明:复合材料对亚甲基蓝的吸附量随pH值的上升而上升,对400 mg/L的亚甲基蓝最佳吸附条件是pH值为10,复合材料使用量为2.0 g/L,吸附温度50℃,吸附时间400 min,此时吸附量为193.91 mg/g,吸附率为96.96%。吸附过程符合Freundlich等温线和拟二级动力学模型,说明吸附为多层吸附和化学吸附。In the process of leather production and p rocessing,keratin was disposed of not fully utilized,resulting in a certain waste of resources.The keratin/phenolsulfonic acid condensate composite was prepared by solution blending method,and its adsorption performance to methylene blue was investigated.The research results showed that the adsorption amount of methylene blue by the composite material increases with the increase of pH value.The optimum adsorption conditions for methylene blue of 400 mg/L of pH value was 10,the amount of composite material was 2.0 g/L,and the adsorption temperature was 50℃,the adsorption time was 400 min,the adsorption amount and adsorption rate were 193.91 mg/g and 96.96%.The adsorption process conformed to the Freundlich isotherm and pseudo-second-order kinetic model,indicating that the adsorption was multi-layer adsorption and chemical adsorption.
