Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Wujiyan Gongye called Preparation of high-purity nickel compound from Ni-containing waste materials, Author is Gu, Heng; Li, Xingying; Zhu, Jianchun; Zhou, Jinyun, which mentions a compound: 13940-83-5, SMILESS is [H]O[H].[H]O[H].[H]O[H].[H]O[H].[Ni+2].[F-].[F-], Molecular F2H8NiO4, COA of Formula: F2H8NiO4.
The process conditions for the preparation of high-purity Ni compounds (NiSO4.6H2O, NiF2.4H2O, Ni(Ac)2.4H2O, and NiO) from Ni-containing waste carbonate by H2SO4 leaching were studied, and a technol. process was proposed. The principle for the purification and extraction of Ni solution in the system of H2SO4 was discussed with phase diagram. The recovery of Ni was 92%, and the quality of the product met the national standard
