摘要： A process for plating metal on plastic substrates, particularly ABS substrates, without the use of chrome containing etchants is disclosed. The process involves (i) etching the plastic substrate in an acidic solution of nitrate ions, and preferably silver ions, (ii) conditioning the substrate in an aqueous solution containing an amine or ammonia, (iii) activating the substrate, preferably with a palladium activator, and (iv) plating the substrate with an electroless plating solution. The process allows for complete adherent electroless plating of plastic substrates, particularly ABS substrates, without the use of chromic etchants.

摘要： A method of maintaining a concentration of sulfuric acid in an electrolyte comprising manganese(III) ions in a solution of sulfuric acid. The method includes the steps of a) removing a portion of the electrolyte from the electrolytic cell to an annex tank; b) treating the removed portion of the electrolyte in the annex tank to remove moisture from the portion of the electrolyte; and c) returning the treated portion of the electrolyte to the electrolytic cell. The removed portion of the electrolyte is treated by passing a dry gas over the surface of the electrolyte in the annex tank to absorb moisture from the electrolyte and restore the concentration of sulfuric acid in the electrolyte.
