poly L-lysine film was prepared on multi-walled carbon nanotubes (MWCNTs) modified electrodes by cyclic voltammetry in phosphate buffer solution.The electrochemical behavior of 4-tert-octylphenol on the poly (L-lysine)/MWCNTs/GC composite modified electrode (PL-lys/MWCNTs/GCE) was studied by cyclic voltammetry.Experiment result shows that the peak currents of linear sweep voltammograms were linear to the 4-tert-octylphenol concentrations over the range of 5.6× 10-6~2.0× 10-4 mol/L.The detection limits was 5.0 × 10-7 mol/L.According to the electrochemical response, PL-lys/MWCNTs/GCE can be used as electrochemical sensor for detection and quantitative analysis of 4-tert-octylphenol and the sample in the environment.
