-mil-125 modified carbon paste electrode application

Application of a carbon paste electrode modified NH2-MIL-125, relates to the technical field of electrochemical detection, graphite powder and NH2-MIL-125 (Ti) solid powder and liquid paraffin milled to a uniform carbon paste, filled into the cavity is adjustable carbon paste electrode chamber afford NH2-MIL-125 modified carbon paste electrode. Under visible light irradiation, photocatalytic oxidation NH2-MIL-125 (Ti) oxidation products of cathodic stripping voltammetry detected Mn2 +, the present invention employs a standard curve to have achieve better sensitivity and selectivity. Mn2 + is applied to the detection of the content of the detection result of the method of atomic absorption spectrophotometry detection results almost the same, the formation of a new method of detecting the content of manganese ions.
