SPECIFICATION
METHOD OF PRODUCTION OF MOLYBDENUM BLUE AT HIGH PURITY AND IN
SOLID STATE
Technical Field
The invention is related to the method of production of molybdenum blue at high purity and in solid state with the areas of use which are important for human and environment such as phosphate analysis in waters, measurement of phosphate quantity for control of eutrophication mechanisms in lakes, ponds and biological life parks, analysis of inorganic phosphate speciesbeing important for development of plant in soil and fertilizer industry, determination of phosphorus and silicon content available in metal and metal ores and geological samples, determination of germanium used in steel industry and of arsenic which is toxic to living creatures, and determination of glucose and o-hydroquinone active substance found in certain drug samples colorimetrically.
Infrastructure of the Invention
Molybdenum blue is being obtained with wet synthesis methods since the very first day on which it was discovered. Examining wet synthesis methods, since these require the use of chemicals of reducing agent which are hazardous to environment and need prolonged periods of purification and their productivity is low, they are not useful methods.
When producing molybdenum blue with wet synthesis methods, the synthesis is ensured to take place by adding metallic, organic or inorganic based reducing agents to acidic solutions of molybdenum (V) salts. In order to obtain pure product after realization of the synthesis, it is required to move away these reducing agents from the medium. These purification processes have important disadvantages like taking too much time, low efficiency and failure to move away the reducing agents from the medium fully.
In our day, molybdenum blue is used in many industrial fields. Some of are phosphate analysis in waters, determination of phosphorus and silicon content available in metal and metal ores, determination of germanium and arsenic, determination of glucose
colorimetrically and determination of and o-hydroquinone active substance found in certain drug samples.
The molybdenum blue obtained using wet synthesis methods used in the existing technique is put up for sale in the market in the form of aqueous solution, not in solid state, due to it contains purification problem. This situation is seen to be an important deficiency for the trade of molybdenum blue.
Looking at the state of the art of the technique:

In the method, a large porous anion exchange resin is procured to contact with a solution containing molybdenum blue in a stirred tank reactor system and absorption of molybdenum blue is intended to be realized. After realization of the absorption, desorption agent is added and desorption process is realized. The method of production of molybdenum blue is realized with a method which is highly different from the invention in the patent document mentioned and by means of a green method. The molybdenum blue produced with the method which is the subject of the invention is in solid state and, with this characteristic of it; it may be used according to the desired intended use.
- The US patent document number US19550480612 mentions about bringing in a different dimension to the solubility of the speciesof molybdenum blue having high solubility in water, and relatively low solubility in organic solvents or which cannot be dissolved. The molybdenum blue species obtained by means of this invention may dissolve in organic solvents, but not in water. This patent document mentions about two different methods. Examining these methods, the disadvantages of the method are additionalprocess steps, use of temperature and the impurities to be caused by chemicals used. The solubility of the product obtained in the method of production of molybdenum blue at high purity and in solid state is highly well in said invention and it has also solubility in certain organic solvents. By means of said method of the invention, molybdenum blue production is realized without the need for additionalchemicals.
- The US patent document number US19580728798 mentions about the studies carried out on development of lubrication compounds containing molybdenum blue. In this document, it is explained that the use of molybdenum blue complexes derived from diethylamido-dodecylphosphate being a lubrication additive develops the performance. Said invention is a method ensuring time saving, with low cost and high efficiency, as being a method of production of molybdenum blue at high purity and in solid state.
- The US patent document number US5512264A mentions about obtaining a new blue molybdenum oxide with oxidative dissolution at 100°C-500°C in gas phase of molybdenum hexacarbonyl. Said invention, which is the method of production of molybdenum blue at high purity and in solid state, is realized by potential scanning in acidic solution medium without the application of temperature differently from the invention said patent document.
Said invention, which is the method of production of molybdenum blue, has been developed in order to eliminate the disadvantages in the existing technique. The problems encountered during the characterization of the molybdenum blue obtained with the existing methods are eliminated with the said method of invention.
Using the method which is the subject of the invention, molybdenum blue is synthesized directly in solid state and at high purity. The fact that it can be synthesized in this way allows for environmentally friendly production along with providing the convenience of use. Furthermore, the realization of the production in a very short time by means of this method of invention shows that the method is advantageous in terms of time as well.
By means of said method of invention, the molybdenum blue production at high purity on the electrode surface is realized without the use of metallic, organic or inorganic based reducing agents and without the need for the purification techniques with cyclic voltammetry method moving from acidic solutions of molybdenum salts. Thus, molybdenum blue production is realized at purity higher than the molybdenum blue obtained with the known synthesis methods within even shorter period of time.
At the same time, the molybdenum blue produced in solid state by means of the method of production of molybdenum blue at high purity and in solid state, which is the subject of the invention, allows for the direct determination of phosphate, arsenic and silicate
analytically. Therefore, by means of this method of invention, molybdenum blue is synthesized in solid state and at high purity for the first time.
The molybdenum blue production techniques available in the existing technique take place in a long period of time like 8 hours, said invention, which is the method of production of molybdenum at high purity and in solid state, is realized in a period less than 1 minute, resulting in contribution to saving of time.
