Abstract

The invention relates to a method for measuring octyl phenol by virtue of an electrochemical sensor. The method comprises the following steps: dispersing Ni-g-C3N4 serving as a modifier into an N,N-dimethylformamide solution, coating dropwise the surface of a glassy carbon electrode with the mixed solution, and drying the glassy carbon electrode to obtain a modified electrode; placing the obtained modified electrode into a solution containing a supporting electrolyte solution and a substance to be measured; performing cyclic voltammetry scanning or differential pulse scanning under the irradiation of an infrared lamp, and determining that octyl phenol exists in the substance to be measured if an electrocatalytic oxidation peak appears. The method has the beneficial effects that the surface of the glassy carbon electrode is modified with a nanometer material with an intensified current signal, and the electrochemical sensor is constructed by the specificity recognition of the nanometer material and octyl phenol; g-C3N4 is doped with other elements or compounds, so that the band gap of g-C3N4 can be changed, the interaction of interlayer atoms can be enhanced, the response duration can be prolonged, and photocatalysis efficiency can be improved.
