|
摘要
以4-氨基苯硫酚为改性剂,对硅胶(SG)进行共价修饰,合成得到了一种对甲醛有结合作用的吸附材料中间体(SG-V-NH)。以丙烯酰胺为功能单体、甲醛为模板、在引发剂等作用下聚合反应,在中间体表面制备分子印迹聚合物,得到一种甲醛吸附剂(SGVN-MIP),采用红外光谱其结构进行表征。通过吸附平衡试验考察其吸附工艺条件和吸附容量。结果表明:该甲醛吸附剂吸附容量Q达到41.3 mg/g,吸附选择性较SG提高了5.60倍。
4-aminothiophenol covalent modified silica gel( SG) intermediate( SG-V-NH) were synthesized and used for the adsorption of formaldehyde,with the template molecule of formaldehyde,functional monomers acrylamide in the presence of benzoyl peroxide cause polymerization and preparation of molecularly imprinted polymer of formaldehyde(SGVN-MIP). The structure was investigated of SGVN-MIP by infrared spectroscopy. And the adsorption properties were studied by the static and dynamic equilibrium adsorption method of SGVN-MIP. Results showed that the SGVN-MIP of adsorption capacity was 41. 3 mg/g,adsorption performance of formaldehyde had a better than acticarbon,renewable and reusable increased by 5. 6 times compared with activated carbon.
