Hunan New Frontier Technology Co., Ltd. products

New Frontier Tech`s diamond electrode system processes micro-etching waste by simultaneously recovering copper and regenerating sodium persulfate. Using diamond`s unique electrochemical properties (highest oxygen evolution potential and most negative hydrogen evolution potential) as the anode within a specialized ion membrane cell, it oxidizes sodium sulfate back to sodium persulfate in the anode chamber while reducing copper ions to metallic copper at the cathode. The treated solution contains <0.5g/L copper ions and >100g/L sodium persulfate - ready for direct reuse in the etching bath.
