| 摘 要： | 通过静态吸附试验,研究了强碱性树脂IRA-400对富马酸的吸附性能。结果表明,该树脂与弱碱性树脂IRA-94相比,受pH值影响较小,在pH=3.5时,该树脂对富马酸具有较好的吸附性能,其静态饱和吸附容量为1.466mmol/g湿树脂;该树脂对富马酸的吸附等温线符合Freundlich等温方程,在298.15K,308.15K和318.15K下的相关系数R2均大于0.99,方程的特征参数n1,属"优惠吸附";吸附过程ΔG0,ΔS0,ΔH0,表明此反应过程是放热的,自发进行的,降低温度有利于吸附反应的发生;吸附动力学研究表明,IRA-400树脂对富马酸的吸附过程主要受液膜扩散控制。

| Abstract: | The adsorption behavior of strong basic resin IRA-400 for fumaric acid was studied through static experiments.The results concluded that,comparing with IRA-94,this resin was less influenced by pH.The optimal pH value for adsorption in the medium of fumaric acid was pH 3.5 and the statically saturated adsorption capacity was 1.466mmol/g wet resin.The adsorption data were correlated with Freundlich isotherm equation,and the correlative coefficients(R2) all exceeded 0.99 at 298.15K,308.15K and 318.15K.Characte... |
