DSA Electrode for Electrowinning

DSA Electrode for Electrowinning

Dimensionally stable Anode (DSA) is used in various industries such as the electrowinning of metals, electroplating, copper-foil production, Chlor alkali electrolysis, chlorate production, cathodic protection, electrosynthesis, and wastewater purification. The dimensionally stable electrode is produced by mixed metal oxide compositions such as iridium, ruthenium, platinum, palladium, tin, and tantalum on a titanium substrate. This DSA electrode retains its shape during operation, as opposed to graphite anodes, which are consumed over time.

Thanks to the low cell voltage and high stability characteristics, a dimensionally stable Anode (DSA) results in lower energy consumption and a long lifetime in the electrowinning process. What’s more, it reduces lead contamination of the cathode product and has been widely used in the electrowinning process.

UTron fabricates DSA electrode for electrowinning using optimum surface pre-treatment of titanium plate and heat treatment. The high-purity of titanium plate was surface treated by blasting, and then the surface oxides were removed in an oxalic acid solution. The titanium plate substrate was treated with anodic oxidation treatment and remove oxidation treatment in order to enhance the lifetime of the DSA electrode. The brushing and thermal decomposition processes were repeated thirty times. The DSA electrode performed high cathode product and purity and pretty long operating life.
