Abstract
The utility model discloses a gold nanometer membrane electrode used for electrolyzing high-purity gold, which comprises a titanium plate and a gold nanometer membrane, wherein the gold nanometer membrane is crystallized on the surface of the titanium plate by an electrolytic preparation method. The nanometer membrane electrode can be used in high-purity gold refining production by asymmetric current to replace a cathode plate manufactured by pure gold. The utility model has the advantages that in the gold electrolyzing process, the gold nanometer membrane electrode can be used for enhancing the purity of cathode gold; by utilizing the characteristic of nanometer gold in the electrocatalysis aspect, the utility model can lower the oxidation-reduction potential, optimize the current density, shorten the production period and reduce gold overstock in production; and thereby, the competition performance of the electrolyzing production is greatly enhanced.
Description
Affiliated technical field
The utility model relates to a kind of gold nano membrane electrode that is used for electrolysis high purity gold.
Background technology
Technologies such as electrolytic process, chemical method and extraction process are mainly adopted in gold refining both at home and abroad.Wherein, the electrorefining of gold is because advantage such as simple, the productive capacity of technical process is stable, operating environment is better and being adopted by most gold refining enterprise, but conventional electrolysis process has following shortcoming: the production cycle long, process kumquat press more, energy consumption big, it is comparatively serious to pollute.
The utility model content
The utility model provides a kind of gold nano membrane electrode that is used for electrolysis high purity gold, its be applied in electrolytic process can overcome in concise the existing production cycle of background technology gold refining long, process kumquat press more, energy consumption big, the deficiency polluted.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of gold nano membrane electrode that is used for electrolysis high purity gold, it comprises that a titanium plate and analyses gold nano film on titanium plate surface by electrolytic preparation method.
In the utility model one preferred embodiment, this gold nano film is the gold nano film of thickness less than 100nm.
In the utility model one preferred embodiment, this gold nano film is the gold nano film of surperficial mean particle size less than 70nm.
In the utility model one preferred embodiment, this gold nano film comprises that a diapire and extends upward the perisporium that forms by the diapire periphery, and this perisporium height equals titanium plate height 1/2-3/4; This diapire is attached to titanium plate bottom surface, and this perisporium coincide and all sides of socket titanium plate.
The technical program is compared with background technology: the nanometer film electrode can be used in the asymmetrical current high purity gold refining production, the negative plate that replaces proof gold to make, it has following advantage: the purity that 1, can improve the negative electrode gold in golden electrolytic process with the gold nano membrane electrode; 2, utilize the character of nanometer gold electrocatalysis aspect, can reduce redox potential, optimize current density, shorten production cycle and the process of minimizing kumquat pressure, thereby strengthened the competitiveness that electrolytic process is produced greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the diagrammatic cross-section of the gold nano membrane electrode that is used for electrolysis high purity gold of the utility model one preferred embodiment.
Embodiment
Please refer to Fig. 1, a kind of gold nano membrane electrode 100 that is used for electrolysis high purity gold, it comprises that a titanium plate 110 and analyses gold nano film 120 on titanium plate 110 surfaces by electrolytic preparation method.The thickness of this gold nano film 120 for example is 90nm, 80nm, 95nm less than 100nm.The surperficial mean particle size of this gold nano film 120 for example is 65nm, 69nm less than 70nm.
This gold nano film 120 comprises that a diapire and extends upward the perisporium that forms by the diapire periphery, and this perisporium height equals titanium plate height 2/3; This diapire is attached to titanium plate bottom surface, and this perisporium coincide and all sides of socket titanium plate.
The gold nano membrane electrode 100 of present embodiment in order in the electrolytic process gold refining process, can be concise be gone out the gold of high purity (99.999%).
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
