The electrochemical behavior of p -chlorophenol (p -CP) with homemade carbon fiber electrode was studied by voltammetry method. The sensitive electrochemical response of p - CP to carbon fiber electrode was observed and can be applied to the determination of p - CP. The effects of sweep speed, pH value and the con- centration on the determination of p - CP were investigated. The experimental result indicates that the behavior of p - CP on carbon fiber electrode is controlled by the adsorption process. Under the optimal condition of determina- tion, in H2SO4 of 1 mol ·L^-1, its oxide peak currents in the range of 5 ×10 -5 - 10 -3mol/L^-1 have well linear relationship with p - CP concentrations, the correlation coefficient is 0. 9981, the detection limit is 1 ×10^-6 mol · L^-1 with RSD of 3. 3% (n=10).
