A pH measurement system is used in many experiments, and the pH electrode plays a vital role as an instrument directly in contact with the solution. What is a pH electrode? PH electrode, also known as PH probe, PH sensor, English name PHelectrode or PHsensor, is the part of the PH meter that is in contact with the substance to be measured, and is used to measure the electrode potential. Working principle of pH electrode There are usually two methods to measure the pH value in aqueous solution, colorimetric method (PH test paper and cuvette) and potentiometric method. The potentiometric method is a method that can realize continuous online measurement and process monitoring, and the potentiometric method can obtain accurate and repeatable pH values. The core theory of pH electrode measurement is the Nernst equation. The electrodes used in potentiometric analysis are called primary cells. A primary battery is a system whose function is to convert chemical reaction energy into electrical energy. The voltage of this battery is called electromotive force (EMF). This electromotive force (EMF) is formed by two half-cells. One of the half-cells is called the measuring electrode, and its potential is related to a specific ion activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and connected to the measuring instrument . The most familiar and commonly used pH indicating electrode is the glass electrode. A set of industrial online pH measurement system usually consists of four parts: pH sensor, namely pH electrode, pH transmitter, electrode sheath and cable. Advantages and characteristics of PH electrode 1. Suitable for biochemical and pharmaceutical processes 2. No need to interrupt during use and can immediately check, clean, and replace electrodes 3. Easy to install and use 4. Handle protection cable connector PH electrode maintenance 1 1. Soak the pH electrode before use, because the pH bulb is a special glass membrane, and there is a thin hydrated gel layer on the surface of the glass membrane. It can only have a good interaction with the H+ ions in the solution under the condition of sufficient humidity response. At the same time, the glass electrode is soaked, which can greatly reduce the asymmetric potential and tend to be stable. 2. The pH electrode should not be soaked in neutral or alkaline buffer solution. Long-term immersion in such solution will make the pH glass membrane slow in response. 3. If it is a composite electrode, it should be soaked in the PH4 buffer solution containing KCL, so that it can act on the glass bulb and the liquid junction at the same time.

Selection of pH electrode and ORP electrode 1. Selection of pH electrode: 1. Selection of shell material: PC plastic (polycarbonate) shell and glass shell are generally used for pH electrode shells. PC shells are resistant to collisions and impacts, but proper temperature<80oC. And it is susceptible to corrosion in high alkali solution and some media. The glass casing is suitable for a temperature of 0-150oC, and is generally not corroded except for hydrofluoric acid solution, but it is easy to be damaged by collision. 2. Selection of the liquid junction: The liquid junction is the connection part that communicates the external reference solution and the measured solution, and requires stable and reproducible potential. Generally, liquid junction materials include fiber material, ceramic core, glass grinding mouth and other media. Fiber material is generally used in plastic case electrodes, and the solution seeps out faster and is not easy to block; the ceramic core has good corrosion resistance, and the liquid junction potential The stability and reproducibility are good, and it can be used in high temperature medium. It is a widely used liquid junction material; the contact area between the glass grinding interface and the solution and the seepage speed are large, and it is suitable for the weak ionic strength. , Determination of high viscosity, turbid liquid or colloidal solution. 3. Selection of pH-sensitive glass membrane: pH-sensitive glass membrane is melt-blown from lithium glass with hydrogen function, generally in a spherical shape, and most electrodes use conventional sensitive glass membranes, but there are still sensitive ones for high-temperature media. Glass membranes, sensitive glass membranes for high-temperature strong acid media, sensitive glass membranes for high-temperature steam sterilization (130oC), and low-resistance sensitive glass membranes (for the determination of pure water), etc., should be selected according to different situations. 4. Selection of reference electrode: Ag/Agcl reference electrode is commonly used, but the general Ag/Agcl reference electrode is easy to dissolve at high temperature and the potential is unstable, while the Ag/Agcl reference electrode with capillary structure has Very stable reference potential, suitable for use under high temperature and long-term continuous testing conditions. 5. Selection of electrode socket: The most commonly used socket for pH electrodes is BNC type (also known as Q9 type), in addition to other types, it mainly depends on the matching of corresponding instruments. (The last letter of the electrode model indicates the socket type). 2. ORP electrode selection: 1. General selection requirements: Same as pH electrodes (except the sensitive membrane) 2. Selection of sensitive components: The selection of ORP electrode sensitive components mainly considers the properties of the measured medium. Generally, gold electrodes are used for Oxidizing media such as oxidation of cyanide, oxidation of nitrite, measurement of ozone, measurement of hydroperoxides. Platinum electrodes are used for reducing media, such as the reduction of chromate, chlorination of swimming pools, etc.
