盐对超高交联树脂吸附苯酚机理的影响
EFFECT OF SALT ON ADSORPTION MECHANISM OF PHENOL ONTO A HYPER-CROSS-LINKED ADSORBENT
【摘要】 以超高交联吸附树脂NDA-101吸附苯酚为例,研究了水溶液中无机盐(NaCl)对吸附的影响规律,探讨了可能的吸附机理,并通过吸附等温线分析及吸附热力学结果给出了合理的解释。同时采用恒定波振荡理论和吸附等温方程联合模型可以很好的拟合相关穿透曲线。
【Abstract】 Adsorption of phenol on a hyper-cross-linked NDA-101 was studied and effect of salt on adsorption was discussed in the present study. Isotherm analysis and thermodynamic results obtained were helpful to get a reasonable adsorption mechanism. Furthermore, a model based on a constant-wave theory and adsorption isotherm equation was fit for the relevant breakthrough curves satisfactorily.
