【摘要】 研究了玉米芯对活性艳红K-2BP染料的吸附性能及吸附动力学.探讨了溶液的初始质量浓度、pH值、时间和温度对吸附性能的影响.研究了吸附规律及动力学,结果显示:其吸附行为满足Langmuir等温式,反应级数为3级,反应速率常数k=1.7783(mol/L)-2.h-1和反应活化能Ea=34.1801 kJ/mol。

【Abstract】 The Adsorption properties and Kinetics of Reactive Brilliant Red K-2BP removed by corncob was studied.The effects of the concentration,pH value,time and temperature on adsorption capacity were investigated.The adsorption law and Kinetic were studied,and the results show that its behavior conforms to the equation of Langmuir,and that the absorption kinetics conforms to the character of the third-order reaction,the reaction rate constant k= 1.7783(mol/L)-2·h-1 and the reactive activation energy Ea=34.1801kJ/mol.
