Voltammetric Behavior And Its Determination Of Acetaminophen At Poly (Congo Red) Modified Electrode, Hong-Bin Luo, Ya-Feng Zhang, Wei Chen, Xin-Hua Lin
Journal of Electrochemistry
Cyclic voltammetry was used to prepare poly(Congo Red) film on glassy carbon electrode and to study the electrochemical behavior of acetaminophen on poly(congo red) modified electrode.Experimental resultal shows that the poly(congo red) modified electrode exhibits excellent electrocatalytic effect on the oxidation of acetaminophen.The peak currents of linear sweep voltammogram are linear to the acetaminophen concentrations over the range of 2.0×10~(-7) ～2.0×10~(-6) mol·L~(-1).The detection limit has been estimated to be 4.0×10~(-8) mol·L~(-1).This method can be used for the determination of acetaminophenin real sample.
