Abstract
The invention concerns a method for the treatment by electrolysis of used photographic solutions, in particular those containing developers for X-ray films, in an electrolysis cell comprising at least one platinum anode and at least one cathode. According to the invention, a current density profile is used, and the current density at the start of electrolysis does not exceed 50% of the maximum density of the electrolysis current. The invention enables the quantity of foam formed during electrolysis to be reduced.
