摘要:A facile and reliable electrochemical technique at β-cyclodextrin incorporated carbon nanotubes modified glassy carbon electrode (β-CD/CNTs/GCE) was proposed for determination of pentachlorophenol (PCP). The electrochemical behavior of PCP at the β-CD/CNTs/GCE was investigated by cyclic voltammetry and linear sweep voltammetry. The β-CD/CNTs/GCE showed good analytical performance characteristics in electrocatalytic oxidation of PCP, compared with the simple carbon nanotube modified electrode (CNTs/GCE) and bare glassy carbon electrode (GCE). After accumulation for 5 min on β-CD/CNTs/GCE, the peak current increased linearly with the concentration of PCP in the range from 8.0 × 10~(-7) to 1.04 × 10~(-5) mol/L. The detection limit was 4.0 × 10~(-8) mol/L at 3σ level. The proposed electrode presented good repeatability for the determination of PCP in artificial wastewater, and the recovery was 97%-103%. This modified electrode combined the advantages of carbon nanotubes and supramolecular cyclodextrin, leading to new capabilities for electrochemical detection of PCP.
