摘　　要：利用g-C_(3)N_(4)与Cs_(x)WO_(3)形成异质结作为电极修饰材料,构建了g-C_(3)N_(4)/Cs_(x)WO_(3)电化学传感器,用于对硝基酚的灵敏高效的快速检测.通过差分脉冲伏安法对该修饰电极检测对硝基酚进行电化学研究.研究结果表明,该电化学分析方法对检测对硝基酚表现出较高的灵敏度,在0.2~50μmol·L^(-1)的浓度范围内呈良好的线性关系,检测限约为0.067μmol·L^(-1),具有较宽的线性范围和较低的检测限,良好的稳定性、重现性和抗干扰能力,可用于实际水样中对硝基酚的测定.Using the heterojunction of g-C_(3)N_(4) and Cs_(x)WO_(3) as the electrode modified material,the g-C_(3)N_(4)/Cs_(x)WO_(3) electrochemical sensor was constructed for the sensitive and efficient rapid detection of p-nitrophenol.The detection of p-nitrophenol at the modified electrode was studied by differential pulse voltammetry.The results showed that the electrochemical analysis method exhibited high sensitivity for the detection of p-nitrophenol and good linear relationship in the concentration range of 0.2~150μmol·L^(-1).The detection limit was about 0.067μmol·L^(-1),with a wide linear range and low detection limit,good stability,reproducibility and anti-interference ability,which is able to be used for the determination of p-nitrophenol in actual water samples.
