Feasibility of regenerating etching acids as part of the metal-etching process

The purpose of regenerating acids and used etching solutions is to return as much of the acid(s) initially added as possible to the etching process. A significant fraction of the unused acid (which makes up from a quarter to a third of the volume of acid initially added to the primary etching bath)...

Summary:The purpose of regenerating acids and used etching solutions is to return as much of the acid(s) initially added as possible to the etching process. A significant fraction of the unused acid (which makes up from a quarter to a third of the volume of acid initially added to the primary etching bath) can be regenerated. Full regeneration is also possible; in practice, however, this is only used for etching baths containing hydrochloric acid. There is currently no universal regeneration technique. A process must be selected for each specific case, taking into account a large number of factors affecting suitability of the process. When selecting processes for use, it is also desirable to reduce adverse environmental impacts.[PUBLICATION ABSTRACT]
