Method for treating brass |
| abstract |
Brass articles having leachable lead are contacted with an aqueous caustic solution having a pH of about 10 to about 14 that contains a chelating agent. During contact, the brass articles can be sonicated. The brass articles can be optionally pretreated by contacting them with an aqueous solution containing an organic carboxylic acid and an inorganic per-salt. The brass article can optionally further be post treated by contacting them with an aqueous solution containing thiourea. |
