Nickel sulfamate is used as an electrolyte in nickel electroplating systems.?? ??
Nickel sulfamate is prepared by heating an aqueous solution of sulfamic acid, H2NSO3H, with fine nickel powder or black nickel oxide under controlled conditions:2H2NSO3H + NiO → Ni(SO3NH2)2 + H2OAt ordinary temperatures, sulfamic acid hydrolyzes slowly forming ammonium bisulfite. However, when heated it hydrolyzes rapidly forming sulfuric acid. Therefore nickel sulfamate should be prepared rapidly before any sulfamic acid hydrolysis occurs due to longer contact time with water.
Nickel sulfamate also can be prepared by the action of sodium sulfamate on nickel carbonate: 2H2NSO3Na + NiCO3 → Ni(SO3NH2)2 + Na2CO3
Nickel sulfamate is usually not isolated from its product mixtures. The product solution is sold for commercial applications.
Safety Profile
Confirmed human carcinogen. Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes of SOx and NOx. See also NICKEL COMPOUNDS.?????? ?? ?? ? ???
