摘要: 以玉米芯为原料制备活性炭吸附剂,研究其对次甲基蓝、碱性品红、甲基橙三种染料废水的吸附性能。考察了温度、吸附剂量、吸附时间等因素对吸附效果的影响。结果表明,在吸附剂量为1g,吸附时间在5h左右,温度为70℃时玉米芯吸附剂对三种染料达到最佳吸附效果。吸附率与时间的吸附动力学方程说明吸附过程有很好的线性关系。玉米芯活性炭作为染料废水吸附剂具有很好的开发应用前景。

Abstract: With corncob as the raw material, activated charcoal absorbent was prepared. Its sorption capicities to three kinds of dye wastewater, namely methylene the blue, the alkalinity pinkish red and themethyl orange were studied. Effects of factors such as temperature, adsorption dosage adsorption time on adsorption were investigated. The results indicated that, on the conditions of the adsorption dosage 1 g, the adsorption time about 5 h, the temperature 70 ℃ corncob absorbent achieves the best adsorption effect to three kinds of dyes. Dynamic equation of the adsorption rate and the adsorption time showed the adsorption process has very good linear relation. Application of the corncob activated charcoal for processing dye wastewater has favorable development prospect.
