초록
The process of recovering copper from industrial brass waste is a significant focus of scientific research, especially as the volume of this waste increases daily due to the frequent use of brass in various industries. This research aims to study the electrochemical behavior of recovering copper in the form of an ultra-fine, high-purity powder using the electrochemical deposition method. Rectangular samples of industrial brass waste, measuring 12 cm in length, 2.5 cm in width, and 1.5 mm in thickness, were used. The electrochemical deposition method involved recovering copper powder using a chemical solution consisting of 1M H2SO4 and CuSO4·5H2O. Different voltages were applied, specifically 0.8, 0.9, and 1 volt, for a constant time period of 30 minutes. The results showed that high purity reached 99.2% at an applied voltage of 0.9 volts, while the maximum deposit of copper powder was 2.5 g at an applied voltage of 1 volt. An ultra-fine copper powder was obtained with a grain size of 4.3 micrometers. The electrochemical behavior also indicated the possibility of precipitating copper and zinc oxides, along with some impurities, during the electrostatic deposition process from industrial brass waste.
