| 中文摘要:
| 从5种树脂中筛选出一种吸附量大的树脂HZ816。研究了HZ816树脂影响吸附及解吸的因素,得出结论如下:HZ816树脂对2-苯乙醇平衡吸附量为151.3 mg/g,最佳吸附pH值为5.1,吸附为快速平衡过程,1.5 h内即达到吸附平衡。通过静态平衡实验及等温线方程,得出HZ816树脂符合Freundlich方程。在不同温度下,HZ816树脂随温度的升高对2-苯乙醇的吸附量下降,表明它对2-苯乙醇的吸附是一个放热过程。最佳洗脱剂为无水乙醇,3倍树脂床体积的洗脱液可基本上将2-苯乙醇从树脂上洗脱下来,而且洗脱峰集中,无明显拖尾现象。

| In this manuscript,the authors chose HZ816 as research model to study the factors which affect the adsorption and desorption capacity.A series of results were achieved by the single factor experiments: the equilibrium 2-phenylethanol adsorption amount of HZ816 is 151.3 mg/g;the adsorption pH value 5.1;to the adsorption balance time 1.5 h.According to the static balance experiment and isotherm equation,it was found that the behavior of HZ816 obeys to Freundlich equation.Meanwhile,the adsorption of 2-phenylethanol is an exothermic process due to the fact that the 2-phenylethanol adsorption amount of HZ816 decreases with the increasing of temperature.The optimum eluent solvent is absolute ethanol.2-phenylethanol can be desorbed completely by eluent solvent of 3 times bed volume,and the eluting peaks are centralized and no obvious trailing phenomenon was detected.
