| Introduction | nickel sulfate: one, two, four, six, seven hydrate and anhydrous, heptahydrate is a naturally occurring bisalum, green transparent crystal. Nickel sulfate heptahydrate loses six molecules of crystal water at 103 ℃, loses all crystal water at 280 ℃ and becomes anhydrous NiSO4, which is yellow-green crystal with specific gravity of 3.68, soluble in water, insoluble in ethanol and ether, it decomposes at 840 °c, loses sulfate, and becomes nickel oxide. |
| recovery preparation | a method for recovering copper and nickel from electroplating sludge, wherein step 1 separates copper is as follows: the leaching solution (hereinafter referred to as mother liquor) was adjusted to pH = 5-5.5 with sodium carbonate solution, and the precipitate was filtered to obtain mainly basic copper carbonate and copper hydroxide. The step 2 iron-nickel coprecipitation and iron are as follows: the mother liquor is adjusted to pH = 8-9 with sodium carbonate solution, and the precipitates are nickel carbonate, iron hydroxide and ferrous hydroxide, the precipitate was completely dissolved by addition of sulfuric acid and hydrogen peroxide, and then adjusted with alkali solution) pH = 5 the precipitate was filtered out, and the precipitate was iron hydroxide. The purification and separation of nickel products in step 3 are as follows: take the above filtered mother liquor and adjust the pH = 2 with sulfuric acid to enter hydrogen sulfide, convert the copper in the mixed solution into copper sulfide and separate it, the mother liquor in this case is a nickel sulfate mother liquor, and nickel sulfate heptahydrate can be produced by a method of concentrating crystallization. |
| Application | nickel sulfate heptahydrate can be used for electroplating, nickel battery, catalyst and preparation of other nickel salts, etc, metal colorants, etc. used in electroplating, nickel battery, catalyst and preparation of other nickel salts, etc., and used in printing and dyeing mordant, metal colorant, etc. used as hydrogenation catalyst, mordant, analytical reagent used in electroplating, nickel battery, catalyst and preparation of other nickel salts, etc., and used in mordant, metal colorant |
| preparation | dissolve the nickel sulfate to be refined in water, add excess concentrated ammonia, all of the nickel was converted into a nickel ammonia complex, and a small amount of hydrogen peroxide was further added thereto, followed by sufficient stirring, and the resulting Fe(OH)3 precipitate was removed by filtration. A concentrated NaClO4 solution was added to the filtrate, at which time Ni2 almost quantitatively produced a [Ni(NH3)6](ClO4)2 precipitate, which was filtered off and washed thoroughly with water. The precipitate was transferred to a beaker, pure sodium carbonate solution was added, and NH3 was evaporated by heating to form a nickel carbonate precipitate. After the mother liquor was separated by decantation, the precipitate was washed repeatedly with distilled water to obtain nickel carbonate as pure as possible. A pure nickel sulfate solution was obtained by dissolving nickel carbonate in dilute sulfuric acid. This solution is concentrated by evaporation and then crystallized at a temperature below 20 ° C. To give crystals of the heptahydrate NiSO4 · 7H2O. |
