摘　　要：为探究玉米秸秆茎髓和玉米芯对亚甲基蓝的吸附规律及最佳条件,以亚甲基蓝为吸附质,天然玉米秸秆茎髓和玉米芯为吸附剂,进行了玉米秸秆茎髓和玉米芯对亚甲基蓝的吸附规律及吸附效果的试验。结果表明：最佳吸附条件为吸附100min,吸附剂用量0.05g,温度30℃,pH10,吸附剂玉米秸秆茎髓80-100目、玉米芯60-80目,玉米秸秆茎髓和玉米芯的亚甲基蓝的初始浓度分别为280 mg/L和300mg/L;准二级动力学方程能够很好地描述玉米秸秆茎髓和玉米芯对亚甲基蓝的吸附过程。The adsorption law and effect of cornstalk pith and corncob to methylthionine chloride were tested to study the adsorption law and optimum condition.The results showed that the optimum adsorption condition includes 0.05 g cornstalk pith with 80-100 mesh to initial methylthionine chloride concentration with 280 mg/L or 0.05 g corncob with 60-80 mesh to initial methylthionine chloride concentration with 300mg/L,at 30℃ and pH 10 for 100min.Quasi second kinetic equation can describe the adsorption process of cornstalk pith and corncob to methylthionine chloride very well.
