description: Tin (Sn) is a widely used metal in various industries, but its processing generates wastewater that pollutes the environment. One method to reduce tin levels in liquid waste is electrodeposition, an electrochemical process that deposits metal ions onto an electrode using direct electric current. This research is highly relevant for the metal processing and electroplating industries, which produce wastewater containing tin ions from their plating processes. This study aims to determine the effect of voltage and acid concentration on the efficiency of tin deposition using the electrodeposition method. Synthetic tin waste was prepared by dissolving Sn in a 0.01 M HCl solution. The electrodeposition process was conducted using a carbon felt cathode and a titanium-platinum anode. The results show that increasing the voltage up to 7.3 Volts increased the deposited Sn mass to 0.4861 grams, with an electrodeposition efficiency reaching 45%. However, efficiency does not always increase linearly due to side reactions, such as the formation of H₂ gas. Additionally, an increase in acid concentration decreased efficiency because of the conversion of Sn²⁺ to Sn⁴⁺, which is difficult to reduce. The optimum voltage was found to be 4.8 Volts, achieving an efficiency of 31%. This research indicates that electrodeposition is effective for reducing tin content in liquid waste when appropriate operating parameters are selected.
