Abstract EN

A sensitive voltammetric method for trace measurements of hydroquinone in the sewage water is described.

The poly-L-histidine is prepared to modify the glassy carbon electrode in order to improve the electrochemical catalysis of interesting substances such as hydroquinone.

The influence of the base solution, pH value, and scanning speed on the tracing of hydroquinone is discussed, and the experimental procedures and conditions are optimized.

The laboratory results show that it is possible to construct a linear calibration curve between the peak current of hydroquinone on modified electrode and its concentration at the level of 0.00001 mol/L.

The potential limitation of the method is suggested by a linear peaking shift model as well.

The method was successfully applied to the determination of hydroquinone in the actual sample of industrial waste water.
