Process for reducing the concentration of carbonate in an aqueous solution and process for etching |
| abstract |
A process for reducing the concentration of carbonate in an aqueous solution is disclosed which includes contacting the aqueous solution with a strongly basic ion-exchange. resin. The process is preferably used for treating aqueous solutions used for etching polyimides which solutions contain an alkali metal hydroxide. |
