[0036] As is known, Chronoamperometry is an electrochemical method. The following is a detailed introduction to it: Chronoamperometry is to apply a constant potential step or a double potential step to the working electrode of the electrochemical system, and then measure the change relationship of the current response over time to obtain a current-time curve (It curve). This method usually uses electrodes of fixed area, such as suspended mercury, platinum, gold, graphite, etc., and is suitable for studying electrode processes of coupled chemical reactions, especially the reaction mechanism of organic electrochemistry. Chronoamperometry is often used in electrochemical research, especially in electron transfer kinetics. It can also be applied to electrochemical sensors, such as analytical determination of hydrogen peroxide, glucose, etc. These sensors are generally "current-type" sensors that detect the concentration of the target substance by measuring the current response. Chronoamperometry has the characteristics of low hardware requirements, strong versatility, good stability and repeatability. It can provide information about electrode reaction kinetics and mass transfer processes. In recent years, chronoamperometry has been continuously improved and expanded. For example, the method of two potential jumps (chronoamperometry with two potential steps) can better observe the kinetic reaction process, and mathematically deduce and plot the reaction rate constant based on the Cottrell equation. In addition, there are studies that have achieved fast and accurate electrochemical detection by improving the electrochemical potentiostat and signal detection circuit.

[0037] Embodiment 1

[0038] The present invention introduces the chronoamperometry into the measurement process, actively applies a voltage signal to the electrode, and then collects the response current signal on the electrode, and reflects the ion concentration information in the measured solution through the current signal. The voltage application time and the time for collecting the current signal of this method are both known, the measurement time is controllable, and the method has strong scalability.

[0039] Based on the above principles, reference Figure 1The detection system for measuring the chloride ion content of the present invention comprises a solution pool, a reference electrode RE, an auxiliary electrode CE, a working electrode WE and a three-electrode test circuit, wherein the reference electrode RE, the auxiliary electrode CE and the working electrode WE are all inserted into the solution pool, the three-electrode test circuit is connected to the reference electrode RE, the auxiliary electrode CE and the working electrode WE, an ammeter A is arranged between the working electrode WE and the three-electrode test circuit, and a voltmeter V is arranged between the working electrode WE and the reference electrode RE. When working, a voltage signal is applied to the working electrode WE, and a response current signal on the working electrode WE is collected at the same time, and the concentration information of the chloride ions in the measured solution is calculated through the response current signal.

[0040] The applied voltage signal and its response current are shown in Figure (b), E H is the detection voltage, and the application time is t 1 , E L is the set voltage, applied for a time of t 2 , which is used to release the charge accumulation of the working electrode WE, reload the diffusion layer, and increase the response current of the electrode. Analysis of the response current signal shows that during the application of the detection voltage, the response current signal increases rapidly, then decreases rapidly, and then tends to stabilize. 1 The response current after stabilization at the end of the time is related to the solution ion concentration and can be used to detect the chloride ion concentration in the solution.

[0041] It should be noted that the present invention can better overcome the shortcomings of passive signal detection and long signal stabilization time in the traditional ion selective electrode method by actively applying voltage signals and collecting response current signals.
