摘要
研究了H-103大孔树脂对水溶液中对硝基苯酚的吸附动力学及热力学特性,通过静态吸附实验,探讨了温度、初始浓度、振荡速度对吸附动力学的影响。该吸附符合一级动力学吸附方程,颗粒内扩散过程是影响吸附速率的主要控制步骤。吸附符合Freundlich等温吸附方程,吸附为放热的物理吸附过程,适当降低温度有利于吸附。
It was investigated that the thermodynamic properties and adsorption kinetics of H-103 macroporous resin to adsorb p-nitrophenol in aqueous solution by static adsorption test, the influence of the initial concentration, temperature and oscillation speed on the kinetics discussed. The results showed that the adsorption coincided with a first-order kinetic adsorption equation and a Freundlich adsorption isotherm equation, the adsorption rate depened on closely diffusion rate within the particles. The adsorption was an exothermic physical one,the temperature reduced properly resulted in the benefit of the adsorption.
