i have a lot of filter papers impreganated with active carbon---these papers was used to filtrate dirty or used plating solutions ----gold,rhodium ,paladium,and silver---whem filtrating the active carbon ADSORBS precious metals ions in its structure---how would one recuperate these pms from the activated carbon? At the moment,i use a semi-open oven,to burn out the carbon as co2,leaving the bulk of the pms for further purification-----Can members,sugest some other methods for this task?
thanks all members and friends for sugestions---my method take many hours in the oven
