摘　　要：A drop of iron magnetic dextran microspheres(IMDM) dispersion with the volume of 6μL was cast on the surface of a glassy carbon electrode(GCE) to fabricate a modified electrode,which showed an excellent electrocatalytic activity for the oxidation of hydroquinone.The effect of the constitute and amount of modified film,the type and pH value of electrolytes on the voltammetric behavior of hydroquinone was investigated to obtain the optimum experimental conditions.Due to its wide linear range,excellent selectivity,stability and reproducibility,The modified electrode can be applied to the electrochemical determination of the hydroquinone.A drop of-iron magnetic dextran microspheres（IMDM） dispersion with the volume of 6μL was cast on the surface of a glassy carbon electrode（GCE） to fabricate a modified electrode, which showed an excellent electrocatalytic activity for the oxidation of hydroquinone. The effect of the constitute and amount of modified film, the type and pH value of electrolytes on the voltammetric behavior of hydroquinone was investigated to obtain the optimum experimental conditions. Due to its wide linear range, excellent selectivity, stability and reproducibility, The modified electrode can be applied to the electrochemical determination of the hvdroquinone.
