摘　　要：采用农业副产品玉米芯吸附处理蓝色染料亚甲基蓝,在单一影响因素基础上,利用正交实验优化了吸附反应的最佳条件。在玉米芯粒径28~40目,溶液pH值=3,亚甲基蓝初始浓度100 mg·L^(-1),料液比为1.5g∶20 mL,吸附温度50℃,超声波搅拌20min时,玉米芯对亚甲基蓝去除率达99.137%。The blue methylene - blue dye was adsorbed by using the agricultural by - products such as corncob, the results of orthogonal optimization experiment based on single factor analysis show that the optimal adsorption conditions were as follows： The particle size of corncob was 28 - 40 mesh, the pH was 3, the initial concentration of methylene - blue was 100 mg ·L^-1, the ratio of solid -liquid was 1g： 20 mL, adsorption temperature was 60℃ ,the time of supersonic wave to stir was 30min, the removal rate of methylene - blue by corncob was up to 99. 137%.
