Application of a novel anodic material with an active layer of lead dioxide to electrochemical regeneration of recycled industrial chromiumbearing solutions is investigated. The regeneration is understood as oxidation of Cr3+ ions retained in the recycled industrial waste to the Cr(VI) state. The developed material is inexpensive, resists corrosion and exhibits excellent operational characteristics.
