Study on the host-guest chemical sensor based on calixarene modification-Determination of p-methylphenol
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.
