HOW “GREEN” ALTERNATIVE ENERGY IS?

Solubility of vanadium (V) oxide and ammonium metavanadate in aqueous ammonia solutions of different concentrations was investigated. Solubility of molybdenum (VI) oxide in aqueous ammonia solutions and in neutral media was studied. The process of dissolution of MoO3 is considered and it is established that it proceeds in three stages. Solubility of nickel (II) oxide in aqueous ammonia solutions was investigated. The joint solubility of vanadium, molybdenum and nickel compounds was studied. It was found out what effect vanadium and тickel compounds have on the solubility of molybdenum compounds. It is shown how the concentration of molybdenum oxide changes when the next portion of ammonium molybdenum is dissolved. Further studies of the sediment are proposed. Studies were conducted on the concentration of vanadium (in terms of V2O5). It was found out how the presence of vanadium and nickel affects the content of molybdenum compounds. It is approved, what effect does the concentration of molybdenum oxide on the scheme of the process. The effect of vanadium and molybdenum compounds on nickel solubility was studied.The effect of molybdenum and vanadium on the solubility of nickel oxide was investigated.It is shown how the solubility of nickel oxide is affected by the presence of two substances, namely molybdenum and vanadium. The effect of nickel and molybdenum compounds on vanadium solubility was studied. Further research was devoted to the effect of only molybdenum compounds on the solubility change of vanadium compounds. In the process of research, an aqueous solution is selected in which the vanadium compounds have the highest solubility. The effect of temperature on the increase of molybdenum oxide concentration in the solution has been studied. It is considered how the pH of the solution changes when free ammonia is removed and how this affects the concentration of vanadium oxide in the solution. The effect of temperature on the increase of molybdenum oxide concentration in the solution has been studied. It is considered how the pH of the solution changes when free ammonia is removed and how this affects the concentration of vanadium oxide in the solution.It is investigated that is the main phase of the sediment formed in the solution, according to x-ray phase analysis.
