| 摘 要： | 成功合成了1-乙烯基-3-氨丙基咪唑四氟硼酸盐,采用核磁共振氢谱、红外光谱和紫外光谱对其结构进行表征.以1-乙烯基-3-氨丙基咪唑四氟硼酸盐离子液体为功能单体,N,N’-亚甲基双丙烯酰胺为交联剂,过硫酸铵和四甲基乙二胺为引发剂,经自由基引发聚合在玻碳电极表面制备聚离子液体膜修饰电极.采用伏安法研究了丁羟基茴香醚在该聚离子液体膜修饰电极表面的电化学行为.结果表明,聚离子液体膜能增强其电化学响应.在优化条件下,氧化峰峰电流与丁羟基茴香醚浓度在1.0×10~(-8)~1.0×10~(-5)mol/L范围内呈线性关系,检出限为8.8×10~(-9)mol/L(R_(SN)=3).

| Abstract: | 1-vinyl-3-aminopropylimidazole tetrafluoroborate( VAPimBF_4) ionic liquid was successfully synthesized and characterized with H-NMR,FTIR and UV/Vis. A polymerized ionic liquid film modified glassy carbon electrode( poly-VAPimBF_4/GCE) was fabricated by using 1-vinyl-3-aminopropyl tetrafluoroborate ionic liquid as functional monomer,N,N'-methylene-bis-acrylamide as cross linker,ammonium persulfate and tetramethylethylenediamine as initiator,undergoing a radical polymerization process. Electrochemical behaviors of butylhydroxyanisole( BHA) were investigated by using voltammetry. The results indicated that the polymerized ionic liquid film could enhance the current response of BHA. Under the optimized experimental conditions,the oxidation peak current was linearly related to BHA in the concentration range from 1.0×10~(-8) to 1.0×10~(-5) mol/L with a low detection limit of 8.8×10~(-9) mol/L( R_(SN)= 3). |
