| 摘 要： | 合成了既含氢键供体 ,又含氢键受体的强亲水性氢键吸附剂—聚 (N—乙烯基乙酰胺 )。通过测定它对水溶液中单宁的等温吸附线 ,利用热力学函数关系计算吸附热ΔHm值 ,证明其吸附机理为氢键吸附。通过测定它对 60 0mgL- 1 以下单宁水溶液的动态吸附性能 ,发现在流速为 3BV/h ,流出液体积为1 0 0BV时 ,单宁的去除率在 90 %以上 ,说明该吸附剂是一种较好的单宁去除剂 ,具有一定的应用价值

| Abstract: | A strongly hydrophilic hydrogen-bonding adsorbent-macroporous cross linked poly (N Vinyl-Acetamide),which contains both hydrogen acceptor and donator-was synthesized.Adsorption mechanism of tanning from aqueous solution onto the adsorbent was investigated by calculating of the differential adsorption heats for various adsorption capacities.These results of the dynamic adsorption of tanning with the initial concentration under 600 mgL -1 showed that the adsorption rate of tanning exceeded 90% when the flow rate was 3BV/h and the effluent volume reached 100BV.Therefore,the adsorbent is excellent in removing tanin from extract of natural products,and has great value in application. |
