| 摘 要： | A new type of calixarene-modified electrode has been prepared by directly coating the surface of a glassy carbon electrode with tetrahydrofuran solution containing 25,26,27,28-tetra-（3-amidino thiopropoxy）-5,11,17,23-tetratert-butylcalix4]arene, and applied to the investigation of electrochemical behavior of phenylenediols. The results showed that the modified electrode could selectively recognize o-phenylenediol, making the over-potential of o-phenylenediol dropped and peak current increased greatly. The anodic peak current is proportional to the concentration of o-phenylenediol in the range of 1.0×10^-5-1.0×10^-4 mol·L^-1 with the detection limit （SIN=3） of 1.0×10^-7 mol·L^-1. The recognizing mechanism, including electrochemical process and binging sites, was also discussed using voltammetry.

| Abstract: | A new type of calixarene‐modified electrode has been prepared by directly coating the surface of a glassy carbon electrode with tetrahydrofuran solution containing 25,26,27,28‐tetra‐(3‐amidino thiopropoxy)‐5,11,17,23‐tetra‐ tert‐butylcalix4]arene, and applied to the investigation of electrochemical behavior of phenylenediols. The results showed that the modified electrode could selectively recognize o‐phenylenediol, making the over‐potential of o‐phenylenediol dropped and peak current increased greatly. The anodic peak current is proportional to the concentration of o‐phenylenediol in the range of 1.0×10?5–1.0×10?4 mol·L?1 with the detection limit (S/N=3) of 1.0×10?7 mol·L?1. The recognizing mechanism, including electrochemical process and binging sites, was also discussed using voltammetry. |
