Chloride ion sensing electrode and preparation method and application thereof

The invention discloses a chloride ion sensing electrode and a preparation method and application thereof. The chloride ion sensing electrode comprises a PVC tube, an epoxy resin cured material filled in the PVC tube and a filiform silver electrode packaged in the epoxy resin cured material, one end of the filiform silver electrode extends out of the bottom surface of the PVC tube, and a first AgCl deposition layer and a second AgCl deposition layer are sequentially arranged on the end face of the end. The compactness of the first AgCl deposition layer is lower than that of the second AgCl deposition layer, and the other end of the filiform silver electrode extends out of a hole reserved in the side wall of the PVC pipe. The chloride ion sensing electrode is high in sensitivity, good in stability, good in durability, simple in structure, simple in preparation process and suitable for large-scale industrial application. 本发明公开了一种氯离子传感电极及其制备方法和应用。本发明的氯离子传感电极的组成包括PVC管、填充在PVC管内的环氧树脂固化物和封装在环氧树脂固化物内的丝状银电极，丝状银电极的一端从P
