Abstract
The method can find application in the chemical industry, in particular in the electrochemical industry in the technological recycling of the components of the waste etching solutions. It includes the treatment of the waste solutions by alkaline reagents such as sodium or potassium base, carbonates of these bases or with aqueous solutions in ratio alkaline cation (sodium or potassium) to general copper from 0.05 to 15 and increasing the temperature of the system where the copper is separated as a copper compound, the desorption ammonia is absorbed to a suitable solution, such as ammonia water, and the chlorine is converted into aqueous solution of alkaline chloride.
