Abstract
The invention belongs to and a kind ofly produce the method for nickel salt, particularly produce the method for multiple nickel salt with the alternating current electrolysis method with electrolytic process.The feature of present method be with alternating-current as power supply, as electrode, carry out electrolysis with acid solution as electrolytic solution, with the nickel plate to obtain certain nickel salt product.The advantage of this method is that equipment is simple, and easy to operate, speed is fast, the current efficiency height, and concentration and purity are easy to control, are a kind of province energy, reduce the nickel salt new process of production that pollutes.
Description
The present invention relates to a kind of method of electrolytic preparation nickel salt, particularly utilize the alternating current electrolysis method to prepare the method for multiple nickel salt.
At present, nickel salt is the important source material that plating, dyeing, pottery, catalyzer etc. are produced.Along with the development of production and construction, the requirement of nickel salt increases day by day.What produce the nickel salt employing now both at home and abroad is chemical reaction method.For example: when producing single nickel salt, be nickel and sulfuric acid (adding a small amount of nitric acid) effect, generate single nickel salt (containing a spot of nickelous nitrate), thereafter reheat carries out pyroprocessing, remove impurity such as nitrogen peroxide, nitrogen protoxide, the drying method that obtains single nickel salt, produce other nickel salt generally all is raw material with the single nickel salt again, react with different acid, utilize the different solubility of nickel salt to carry out Crystallization Separation again.For example, nickelous oxalate utilizes single nickel salt and oxalic acid reaction back to generate the nickelous oxalate precipitation exactly, forms after separate.Because the proceed step by step and the reacted purification of chemical reaction, the refining discontinuity that waits operation, make this chemical reaction method have the cycle long, consume is big, cost is high, at each production link significant loss is arranged all, can introduce partial impurities again, purity is difficult to shortcomings such as control, also can cause the public hazards of chemical pollution simultaneously.Direct current solution electrode is very easily polarization again, and in industrial production, producer should not adopt.
The present invention's purpose is to produce the weak point that nickel salt technology exists at aforementioned chemical reaction method, discloses the method that a kind of alternating current electrolysis legal system is equipped with nickel salt.The energy of present method is alternating-current, but continuous production, energy consumption is little, and cost is low, and product purity is high and be easy to control, is suitable for suitability for industrialized production.
The present invention's purpose realizes in the following way: make electrode with the nickel plate, acid solution is an electrolytic solution, and acid-resistant container is an electrolyzer, feed alternating-current,, promptly have the nickel salt crystal in electrolyzer, to separate out through certain hour, thereafter leach crystal, mother liquor recycles after being mixed with finite concentration again.
The present invention's purpose also can realize in the following way: in implementing aforementioned technological process, can the solution in the electrolyzer be heated, voltage and current density are to improve its crystalline formation speed between the change plate.
Positively effect of the present invention is: the alternating-current solution is extracted nickel salt and is compared with chemical reaction method that to have equipment simple, easy to operate, and speed of response is fast, current efficiency height, the concentration of solution and the purity of nickel salt are easy to control, and the cost of product is low, because of its solution is to recycle, pollution-free substantially.
Accompanying drawing is a process flow sheet of the present invention.
Below be example with the preparation nickelous oxalate, the present invention's processing method is described further.Saturated oxalic acid solution 60750cm packs in the acid proof electrolyzer
3, to insert nickel plate in the electrolyzer as electrode, feed industrial-frequency alternating current, regulating voltage, control current is about 100 peaces, electrowinning process was through one hour, cut off the electricity supply then, take out electrode, non-shock chilling one hour, can obviously observe a large amount of nickelous oxalates and be deposited in bottom of electrolytic tank, isolate the nickelous oxalate crystallization with decantation then, drying again, get final product 10 kilograms nickelous oxalate product.And then mother liquor is mixed with finite concentration recycles.
Claims (3)
1, a kind of alternating current electrolysis prepares the method for nickel salt, it is characterized in that: with the nickel plate is electrode, and acid solution is an electrolytic solution, acid-resistant container is an electrolyzer, feeds alternating-current, through certain hour, promptly there is nickel salt in electrolyzer, to separate out, recycles after then mother liquor being mixed with finite concentration.
2, prepare the method for nickel salt as the said alternating current electrolysis of claim 1, it is characterized in that: in technological process, the solution in the electrolyzer is heated.
