An ion-exchange membrane electrolyzer is a common electrochemical device used to electrolyze various solutions, such as brine, acidic solution, etc. Its working principle is to use the ionic membrane to divide the electrolytic cell into two electrolytic chambers, place the anode and the cathode respectively, and decompose the ions in the solution into atoms or molecules through the electrolytic reaction, so as to realize the electrochemical reaction.
Ionic membrane is a special membrane with good ion selectivity and electrolyte barrier performance. In the ionic membrane electrolyzer, the ionic membrane divides the electrolytic cell into an anode chamber and a cathode chamber to prevent the mixing of cations and anions, thus ensuring the effective progress of the electrolysis reaction.
In an ion-exchange membrane electrolyzer, the anode and cathode are respectively connected to a power source to form an electric field. When the cations and anions in the electrolyte enter the ionic membrane, they will be separated, and only the same kind of ions can pass through the ionic membrane and enter the corresponding electrolytic chamber. In the anode compartment, the cations accept electrons and undergo an oxidation reaction to produce oxygen or other oxides. In the cathode chamber, the anions lose electrons and undergo a reduction reaction to generate hydrogen gas or other reducing substances.
Ion membrane electrolyzer is widely used in chemical industry, metallurgy, environmental protection and other fields. For example, it can be used to produce chlor-alkali chemicals such as sodium hydroxide, chlorine and hydrogen, etc. In this process, the electrolyte is brine, and the brine is decomposed into substances such as sodium hydroxide, chlorine and hydrogen through the electrolysis reaction of the ion-exchange membrane electrolyzer. In addition, the ionic membrane electrolyzer can also be used in wastewater treatment, metal electroplating, electrolytic aluminum and other fields.
