摘要
以雌酚酮为模板剂 ,以丙烯酰胺和对乙烯基苯甲酸为单体合成出用于分离雌酚酮的新型复合吸附剂。对制备该吸附剂的最佳工艺条件进行了筛选。实验结果表明 :该吸附剂具有三维网状结构 ;对雌酚酮的最大静态吸附容量为 14 .6mg/ g ;最大比表面积为 2 6 4m2 /g ;最大孔径分布为 12nm左右 ;达到吸附平衡的时间为 8h ;符合Langmiur等温吸附规律。因此对雌酚酮具有较好的记忆选择性能、较高的吸附容量和吸附速率 。
New composite sorbents for separating estrone were synthesized with the monomers of acrylamide and p-vinylbenzoic acid using estrone as the template. The optimum preparation conditions for preparing the composite sorbents were selected. The experiment results show: the new composite sorbents are in three-dimensional net stru-cture; the max. static adsorption capacity is 14.6 mg/g for estrone; the max. specific surface area is 264 m^2/g; the max.distribution of pore diameter is about 12 nm; the adsorption equilibrium time is 8 h; and the adsorption rule accords with Langmiur. Therefore,new composite sorbents have a good memory selection property and higher adsorption capacity and rate for estrone, which are fit for its selective separation.
