Abstract
The present invention concerns a process for the electrolytic extraction of the tin found a quantity of less than 1 g/l and in a chelated form in organic solutions. The process consists of using an electrolysis unit comprising an anode compartment and cathode compartment separated by a physical barrier, introducing the organic solution into the cathode compartment and carrying out the electrolysis in galvanostatic or potentiostatic mode. This process can be applied to the recycling of photographic effluents containing tin, in particular to the processing of reversal products.
