The invention relates to an electrolyte solution for electrolyzing a diamond synthesis column. The electrolyte solution comprises the following components in compounding ratio: for each ton of water, 10-50kg of ammonium chloride, 10-30kg of a boracic acid, 0.5-30kg of an oxalic acid, and 1-10kg of sodium nitrate and water are contained. The electrolyte solution for performing column forming and electrolyzing on the diamond synthesis column is stable in solution performance, is high in metal recovery rates, and is high in the loosing speed of the synthesis column. The raw materials are simple, the sources are rich, the operation is simple and the cost is low.
Description
[technical field]
The present invention relates to a kind of electrolytic solution, when being specifically related to a kind of diamond synthesizing column electrolysis, electrolytic solution and using method thereof, belong to artificial diamond purifying technical field.
[background technology]
In existing diamond industry, the technique that diamond is separated from catalyst, graphite is called purifying technique.The concrete mode of this technique (is limited not destroy diamond crystals) after synthesis post is broken into certain particle size, load anode cloth bag and carry out electrolysis, dissolving metal in Synthetic block is enter electrolytic solution after metal ion by electrolytic solution, then on negative plate, electric discharge is reduced into metal, remaining graphite and diamond again through ball milling (or spreading), sieve, oversize about has about 10% to return to re-electrolysis again, and separation by shaking table is sent in minus mesh, and diamond is separated with graphite, catalyst.
Can obtain from above-mentioned explanation, the core of purifying technique is " electrolytic synthesis block ", and electrolytic solution used affects whole technique during electrolysis, because the effect of electrolytic solution is synthesis post to be dipped to rarefaction, again metal solvent is separated from graphite and diamond simultaneously.Metal solvent relies on electrolytic solution to enter cloth bag lentamente, penetrates in Synthetic block and carry out oxidizing reaction with the metallic surface of coming out, make metal with Fe
2+, Ni
2+plasma species enters electrolytic solution.But current electrolytic solution unit price is exactly about 10000 yuan/ton, other materials is also very valuable, and it is longer that synthesis post is dipped to rarefaction required time, and re-electrolysis proportion is comparatively large, makes adamantine manufacturing cost greatly increase like this.
Therefore, for solving the problems of the technologies described above, necessary electrolytic solution and using method thereof when providing a kind of diamond synthesizing column electrolysis, to overcome the described defect in existing electrolytic solution.
[summary of the invention]
For solving the problem, the object of the present invention is to provide a kind of cost low, solution property is stablized, the electrolytic solution when diamond synthesizing column that refining effect is good becomes post electrolysis.
For achieving the above object, the technical scheme that the present invention takes is: electrolytic solution during a kind of diamond synthesizing column electrolysis, it comprises following component: ammonium chloride, boric acid, oxalic acid, SODIUMNITRATE, water, the proportioning mode of each component is: in water per ton, ammonium chloride 10 ~ 50kg, boric acid 10 ~ 30kg, oxalic acid 0.5 ~ 30kg, SODIUMNITRATE 1 ~ 10kg.
During diamond synthesizing column electrolysis of the present invention, electrolytic solution is further: described ammonium chloride, boric acid, oxalic acid, SODIUMNITRATE are solid crystals, and purity is more than 99%.
Also can be with electrolytic solution during diamond synthesizing column electrolysis of the present invention: in water per ton, ammonium chloride is specially 40kg; Boric acid is 30kg; Oxalic acid is 20kg, and SODIUMNITRATE is 10kg.
Another object of the present invention is to, the object of the present invention is to provide the using method of electrolytic solution during a kind of diamond synthesizing column electrolysis.
For achieving the above object, the technical scheme that the present invention takes is: the using method of electrolytic solution during a kind of diamond synthesizing column electrolysis, and control the temperature of electrolytic solution at 60 DEG C ~ 70 DEG C, regulating voltage is to 17-20v, and electric current reaches 1500-1800A; Voltage is maintained 17-20v, if electric current does not reach 1500-1800A, or has downtrending along with the prolongation electric current of electrolysis time, then should add electrolytic solution to current stabilization; If electric current constantly increases, then to take out part electrolytic solution, or thin up electrolytic solution.
During diamond synthesizing column electrolysis of the present invention, the using method of electrolytic solution is further: when there being chlorine to volatilize, and need add ammonium chloride wherein, until taste disappears.
During diamond synthesizing column electrolysis of the present invention, the using method of electrolytic solution also can be: when there being ammonia to volatilize, and need add hydrochloric acid wherein, until taste disappears.
Compared with prior art, the present invention has following beneficial effect: electrolytic solution when diamond synthesizing column of the present invention becomes post electrolysis, and solution property is stablized, metal recovery rate is high, and synthesis post loosens speed soon, and starting material are simple, abundance, simple to operate, cheap.
[embodiment]
Electrolyte prescription when the present invention is a kind of diamond synthesizing column electrolysis, it comprises following component: ammonium chloride, boric acid, oxalic acid, SODIUMNITRATE, water, and the proportioning mode of each component is: in water per ton, ammonium chloride 10 ~ 50kg, boric acid 10 ~ 30kg, oxalic acid 0.5 ~ 30kg, SODIUMNITRATE 1 ~ 10kg.
Specific embodiment and result are as following table
Electrolytic solution during diamond electrolysis of the present invention, in use supplements electrolytic solution wherein without the need to timing, and only in the process used, need add corresponding ammonium chloride or hydrochloric acid for the chlorine that may volatilize, ammonia, solution property is stablized.
Electrolytic solution of the present invention, makes diamond synthesizing column Cheng Zhu be dipped to rarefaction and only needs about 4 days, and use other electrolytic solution to take 5-7 days at present.
Electrolytic solution of the present invention, and the sieving materials of about the 5-7% that only has an appointment need return to re-electrolysis again, lower than about 10% of current electrolysis liquid, and metal recovery amount is also very high, and substantially can maintain the operation cost of this operation, refining is effective.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
