REMOVING ARSENIC FROM A SULPHURIC ACID SOLUTION

The present invention relates to a method for removing arsenic from a sulphuric-acid solution by electrolytically precipitating the solution. The employed current density is adjusted by observing the arsenic and copper contents of the solution with a solution analyser, so that operation takes place...

Zusammenfassung:	The present invention relates to a method for removing arsenic from a sulphuric-acid solution by electrolytically precipitating the solution. The employed current density is adjusted by observing the arsenic and copper contents of the solution with a solution analyser, so that operation takes place below the limiting current density peculiar to each system.
