Pernate extraction from molybdenum oxide samples and synthesis of rhenium oxidenanoparticles and investigation of its application to remove methylene blue

There are many molybdenum compounds with copper minerals. In addition to molybdenumcompounds, rhenium compounds are also found, which due to the increasing use of rhenium, it is necessary toseparate these compounds and make nanoparticles and investigate their application. Here, rhenium oxidenanoparticles were synthesized by chemical precipitation method from molybdenum oxide dust. The averagesize of synthesized nanoparticles was ۴۰.۹ nm. Rhenium oxides are used in industry for many applications.Among the applications of rhenium oxide nanoparticles is their use as a catalyst in removing environmentalpollutants such as organic dyes. Here, the effect of these nanoparticles on the removal of methylene blue, whichis included in the category of aromatic compounds of environmental pollutants, was investigated. The effect ofeffective variables on removal was investigated. The results of the influence of different parameters such as pH,temperature, catalyst amount and intensity of ultrasonic waves on the methylene blue removal process wereinvestigated. The parameters were optimized. In optimal conditions (۵ mg of rhenium oxides nanoparticles,power intensity of ۲۵۰, pH=۱۰), they were able to remove more than ۹۰% of methylene blue in ۱۰ ml of aqueoussolution with a concentration of ۵ μg/ml.
