制备和表征了胺基修饰的超高交联聚苯乙烯吸附树脂,结构特征研究表明树脂具有较高的比表面、丰富的微孔和碱性极性基团等优点。比较研究了树脂对水体系中两类芳香酚(苯酚和邻硝基苯酚)的静态吸附性能,结果表明吸附过程呈现放热特征,树脂对疏水性更强的邻硝基苯酚具有更优的吸附性能。吸附平衡数据均可采用Langmuir和Freundlich吸附等温方程进行较好的拟合,结果表明树脂对两类芳香酚的吸附均为优惠吸附,且呈现出物理吸附为主,弱化学吸附为辅的吸附机理。
製備和錶徵瞭胺基脩飾的超高交聯聚苯乙烯吸附樹脂,結構特徵研究錶明樹脂具有較高的比錶麵、豐富的微孔和堿性極性基糰等優點。比較研究瞭樹脂對水體繫中兩類芳香酚(苯酚和鄰硝基苯酚)的靜態吸附性能,結果錶明吸附過程呈現放熱特徵,樹脂對疏水性更彊的鄰硝基苯酚具有更優的吸附性能。吸附平衡數據均可採用Langmuir和Freundlich吸附等溫方程進行較好的擬閤,結果錶明樹脂對兩類芳香酚的吸附均為優惠吸附,且呈現齣物理吸附為主,弱化學吸附為輔的吸附機理。

The hypercrosslinked polystyrene adsorbent was prepared By Friedel-Crafts post-crosslinking reaction with Trimethylamine. According to the adsorption experiment in aqueous solution, the adsorption capacity of o-nitrophenol with high hydrophobicity is bigger than that of phenol. Fitting data shows that adsorption of phenol and o-nitrophenol on resin fitted well to Langmuir and Freundlich model. The adsorption mechanism technology is mainly based on chemical adsorption, and partially based on physical one.
