摘要
采用三步化学合成法制备了复合纳米粒子还原氧化石墨烯包裹二氧化硅球负载二氧化铈粒子(CeO_(2)/ERGO/SiO_(2)),采用X-射线粉末衍射技术(XRD)对其进行了表征,并用其制备修饰电极,研究了双酚A在该修饰电极上的电催化活性,在优化条件下,双酚A的浓度和氧化峰电流在5.0~100μmol/L范围内呈线性关系,检出限为3.0μmol/L。
The CeO_(2)/ERGO/SiO_(2) nanoparticles were prepared by chemical synthesis method,and characterized by X-ray powder diffraction(XRD)and used tuo prepare modified electrode.The electrocatalytic activity of bisphenol A on the modified electrode was studied.Under the optimized conditions,the concentration of bisphenol A and the oxidation peak current were at 5.0~100μmol/L.The detection limit was 3.0μmol/L.
