| Abstract. | The results of the investigation of electrochemical regeneration of chemical-plated solutions are described. It is noted, that methods of simple chemical regeneration of such solutions are not effective. In this case intensive sedimentation is used. The introduction of nickel ions by electrolysis with the help of nickel anoles disrobe form scolimentation too. To prevent it the addition of acid for value 4,1-4,4 pH was made. With the next introduction in the solution NaH2PO2 5-6 regeneration cycles were reached. Most advanced variant is to connect with dissociation NaH2PO2 in the small quantity of water with a pH value about 2.0 That primary solution is entering in the base solution. Such method provides 11-12 regeneration cycles. The nickel corer from regeneration solutions have such any corrosion properties as corer forming from new solutions and it have such adhesion too. |
