Abstract

The invention discloses a polymerized reactive brilliant orange K-7R membrane electrode which structurally comprises a graphite rod and a polymerized reactive brilliant orange K-7R membrane wrapping the surface of the graphite rod, wherein copper wires are connected to two ends of the graphite rod; the copper wires are fixed on the graphite rod through rubber clamps. The invention further discloses a preparation method of the polymerized reactive brilliant orange K-7R membrane electrode. The preparation method specifically comprises the following steps: 1, preparing a graphite electrode, and 2, preparing the polymerized reactive brilliant orange K-7R membrane on the graphite electrode. The problems that a conventional pH meter is high in detection cost and complete to operate are solved. The invention further discloses a method for the pH detection by using the prepared polymerized reactive brilliant orange K-7R membrane graphite electrode. The method specifically comprises the following steps: 1, connecting the prepared polymerized reactive brilliant orange K-7R membrane graphite electrode according to a zero current potential system device, and 2, performing the detection and the calculation on the pH of a sample solution according to a relationship equation, EZCP=a-bM, between the zero current potential EZCP and the concentration of p-chloroaniline.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection materials, and in particular relates to a polyactive bright orange K-7R membrane electrode. The invention also relates to a preparation method of the polyactive brilliant orange K-7R membrane electrode and a method for detecting pH value under a zero current potential system using the prepared polyactive brilliant orange K-7R membrane electrode. Background technique [0002] The main disadvantages of the currently used pH meters are that the operation is cumbersome, the materials of the supporting electrodes are relatively expensive, and after several times of use, the electrolyte in the electrodes needs to be replenished manually, the electrodes are polluted and the reliability is low. Zero current potential is a new type of interface potential sensing technology. It is not necessary for the system to be detected to contain substances with voltammetric response signals. The magnitu...
