摘要:
通过不同温度下的静态吸附实验,研究了活性炭吸附ADN的动力学和热力学特征。以吸附量和解吸率为指标对3种活性炭(AC、BC、CC)进行对比研究,利用准一级动力学模型、准二级动力学模型和颗粒内扩散模型考察了ADN的吸附动力学,并利用Langmuir和Freundlich吸附等温模型描述吸附热力学行为。结果表明,活性炭AC是分离ADN的理想吸附剂,3种活性炭吸附ADN的动力学曲线更符合准二级动力学模型;Freundlich模型描述活性炭AC对ADN的吸附规律更为合适,该吸附△G<0,△S>0,吸附过程可自发进行;不同吸附量下的△H>0,吸附为吸热过程。
Abstract:
The adsorption kinetics and thermodynamic characteristics of ADN on activated carbons were conducted through static adsorption experiments at different temperatures. The adsorption capacity and desorption rate of three kinds of activated carbons(AC,BC,CC) were compared. The adsorption kinetics of ADN were investigated by using quasi-first-order kinetic model, quasi-second-order kinetic model and intra-particle diffusion model, respectively, and the adsorption thermodynamic behavior was described by using Langmuir and Freundlich adsorption isothermal models. The results show that the activated carbon AC is an ideal adsorbent for ADN separation. The kinetic curves of ADN adsorption by three kinds of activated carbons are more in line with the quasi-second-order kinetic model. It is more suitable to describe the adsorption law of ADN on activated carbon AC by using Freundlich model. This adsorption process can be spontaneous for △G<0, △S>0, and △H>0 under different adsorption amounts, which is an endothermic process.
