【摘要】 以C 十一烷基间苯二酚杯 (6 )芳烃作为主体分子修饰玻碳电极表面 ,制成一种主客体化学传感器。并用其对溶液中的客体分子———对甲酚进行测定。该电极具有良好的选择性 ,对 5 .0× 10 - 5～ 2 .0× 10 - 3mol L的对甲酚具有很好的线性响应 ,检测下限为 3.0× 10 - 5mol L .同时 ,对修饰前后玻碳电极的表面状态进行了研究 .更多还原

【Abstract】 Calixarenes are a kind of host molecular with excellent selectivity. C-undecylcalix(6)- resorcinarene was chosen to modify on the glass carbon electrode to develop a host-guest chemistry modified electrode, which is used to determinate the guest molecular-P- me- thylphenol in the solution. The modified electrode has better selectivity. The line range is 5.0×10 -5 ～2.0×10 -3 mol/L and the detection limit is 3.0×10 -5 mol/L. The surface state of glass carbon electrode is also investigated before and after modification.更多还原
