Purification of washing metal containing solutions of the automated lines of electroplating by electrolysis on iso- and nonisoelectroconducting carbon fibrous electrodes

Process electrolytic extraction of copper from sulfuric solutions of rinse tank of the automated line of electroplating is investigated. Copper sedimentation was carried out on carbon fibrous electrodes (CFE) from a constant and a variable conductivity on a thickness of an electrode. Dynamics of copper deposition of depending on initial CFE conductivity, of current density, rate of solution flow, profile conductivity on a thickness of an electrode is studied. Use iso- and nonisoelectroconducting CFE allows to take copper with a current efficiency and rate of its deposition, provides its low maintenance in washing solutions and return of copper to process.
