Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Poly (crystal violet) film modified electrode was prepared by the electrooxidation of crystal violet on a glassy carbon electrode. The electrochemical behavior of hydroquinone and catechol on the modified electrode was investigated with respect to different solution acidity, scan rate, and accumulation time. The modified electrode showed nice electrocatalystic behaxiors towards the oxidations and reductions of hydroquinone and catechol. Under the optimum experimental situation, the linear calibration ranges were 4×10-6 mol·L-1 to 2.8×10-4 mol·L-1 for hydroquinone and catechol, with detection limits of 6.2×10-7 mol·L-1 and 9×10-7 mol·L-1, respectively. This method was applied to the direct determination of hydroquinone and catechol simultaneously in tap water samples.
