Electrodeposition techniques

Definition

Electrodeposition techniques are methods used to deposit a layer of material onto a substrate using an electrical current, often employed in the field of radiochemistry for the separation and purification of radioactive isotopes. This process utilizes the electrochemical reactions occurring at the electrodes, allowing for precise control over the deposition of materials. In radiochemical applications, these techniques can enhance the purity of isotopes and improve the efficiency of separation processes.
