| 摘 要： | 测定了GDX-502树脂对水中9种一元酚的动态吸附曲线和吸附容量,讨论了可能的吸附机理?实验结果表明,水中各种酚对GDX-502存在着竞争吸附,若水样体积足够大,则水也参与竞争吸附?浓度高的酚,竞争能力强,被吸附容量大?相同浓度的酚,溶解度越小,偶极矩适当大,并能做为电子受体与树脂形成较强的π-键合作用力,则竞争占优势,被吸附容量大?动态吸附曲线上负吸附现象的存在是竞争吸附,特别是水处于优势吸附时的结果

| Abstract: | The dynamic adsorption curve and adsorption capacity of GDX-502 resin for nine mixed monophenols from water were determined by reverse-phase HPLC method,and the adsorption mechanism was discussed briefly.Experimental results reveal the molecular structure and properties of monophenols as well as volume of aqueous solution significantly affect their competitive adsorption ability. |
