elektrolízisberendezés

Elektrolízisberendezés refers to an apparatus used for electrolysis, the process of using an electric current to drive an otherwise non-spontaneous chemical reaction. These devices typically consist of an electrolytic cell, a power source, and electrodes. The electrolytic cell contains an electrolyte, which is a substance that conducts electricity when molten or dissolved in a solvent, and is usually an ionic compound. Two electrodes, an anode (positive electrode) and a cathode (negative electrode), are immersed in the electrolyte.

When a direct current is applied from the power source, ions within the electrolyte migrate towards the electrodes. Positively charged ions, called cations, move towards the cathode, where they gain electrons and undergo reduction. Negatively charged ions, called anions, move towards the anode, where they lose electrons and undergo oxidation. This transfer of electrons at the electrodes causes the chemical decomposition or synthesis of substances.

Elektrolízisberendezések are employed in various industrial applications. A prominent example is the production of aluminum through the Hall-Héroult process, where aluminum oxide is electrolytically reduced. They are also used in the chlor-alkali process to produce chlorine gas, hydrogen gas, and sodium hydroxide. Furthermore, electrolysis is utilized for electroplating, refining metals like copper and nickel, and in some water purification systems to produce disinfectants. The design and materials used in an elektrolízisberendezés depend on the specific chemical process it is intended for, considering factors like current density, voltage, temperature, and the corrosive nature of the electrolyte.
