摘　　要：以C—十一烷基间苯二酚杯 (6 )芳烃作为主体分子 ,修饰玻碳电极上制成的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 -3 mol/L的对甲酚具有很好的线性响应 ,检测下限为 3.0× 10 -5mol/L 。Using C-undecylcalix(6)-resorcin as host molecular to modify the glass carbon electrode, a host-guess chemical sensor is obtained, which is used to determine the guest molecular-p-methylphenol 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 low detection limit is 3.0×10^(-5)mol/L. The surface state of glass carbon electrode is also investigated before and after modification.
