摘要
研究了三乙烯四胺化交联聚苯乙烯螯合树脂对铜离子的吸附动力学、热力学等吸附性能.结果表明,动力学吸附过程为液膜扩散控制;温度对饱和吸附量没有显著影响;吸附过程符合Langmuir和Freundlich模型.吸附活化能(Ea),ΔG,ΔH分别是19 050,-5 658,-8 540kJ/mol;ΔS为9 670J/(mol·K).
The adsorption kinetics, thermodynamics of crosslinked polystyrene-supported triethylenetrtramine resin for Cu^(2+) are investigated. The temperature has an inconspicuousness effect on the saturated adsorption capacity of resin for Cu^(2+). The results show that the adsorption kinetic is controlled by liquid film diffusion. The adsorption process can be described by Langmuir and Frundlich models. The apparent activation energy(Ea),ΔG,ΔH, entropy change are 19.050,-6.984,-2.929kJ/mol,ΔS is 13.608J/(mol·K).
