摘要: 采用静态吸附法研究了D151阳离子交换树脂对Zwittermicin A的吸附过程的热力学性质。 结果表明,在温度288、298和318 K和研究的浓度范围内,Zwittermicin A在D151阳离子交换树脂上吸附等温线均符合Freundlich吸附等温线方程。 热力学参数表明,吸附过程是自发的、放热的优惠型吸附。

Abstract: Thermodynamics of the adsorption of Zwittermicin A by D151 cation exchange resin was studied using a static adsorption method. Adsorption equilibrium data for the adsorption of Zwittermicin A at 288 K, 298 K, 318 K and investigating concentration range were obtained and found to follow the Freundlich-type isotherm equation. The results indicated that the adsorption process of Zwittermicin A by D151 cation exchange resin was a spontaneous, exothermic and favorable adsorption.

Key words: Zwittermicin A, Cation-exchange resin, thermodynamic properties
