摘要
测试检验和理论分析说明在Langmuir方程应用中将平衡吸附量Qe表达为离子起始浓度C0和介质用量W0的函数时,Qe=W0qmC0/(KC+C0),方程式中系数KC不是常数,而是W0的函数并与W0呈线性相关.在蛭石铵离子吸附关系式中,Langmuir方程适用的范围是起始浓度C0较小.
Tests and theoretical analysis indicate that when the total quantity of NH^+_(4) adsorption by vermiculite minerals,Q_(e) is expressed as a function of initial NH^+_(4) concentration C_(0) and medium mass quantity W_(0), using Langmuir Equation Q_(e)= W_(0)q_(m)C_(0)/(K_(C)+C_(0)),the coefficient K_(C) in the equation is not a constant but a function linearly related to W_(0). The suitable range of Langmuir Equation application for description of NH^+_(4) adsorption by vermiculite is within relatively low C_(0) levels.
