The extraction of rhenium from molybdenite roasting dust leach solution was performed using a mixersettler extractor by tributyl phosphate (TBP) diluted in kerosene as the extractant. In the single-stage extraction experiments, effect of the aqueous to organic phase ratios, Qa/Qo, and the number of extraction stages, N, on the rhenium extraction was studied. It was found that using the phase ra...
A series of sodium borosilicate glasses were synthesized with KReO4 or Re2O7, to 10,000 ppm (1 mass%) target Re, to assess effects of large concentrations of rhenium on glass structure and fto estimate solubility of Tc, a radioactive component in low active waste nuclear glasses. Rhenium was used as a surrogate for Tc for laboratory testing, due to similarities in chemistry, ionic size, and red...
We demonstrate that reactions confined within single-walled carbon nanotube (SWCNT) channels are modulated by the metallic and semiconducting character of the hosts. In situ Raman and X-ray absorption near-edge structure spectroscopies provide complementary information about the electronic state of carbon nanotubes and the encapsulated rhenium species, which reveal electronic interactions betwe...
AIM To study the efficacy of novel rhenium compounds to treat triple node negative breast cancer. PLACE AND DURATION Six (6) novel rhenium pentycarbanato compounds (PC1-6) were synthesized and triple node negative breast cancer cell lines HTB-132 and Balb/c mouse kidney cell lines were treated with each of them for 48 hours. The results were analyzed by a common trypan blue cell death assay s...
The quest to create superhard materials rarely strays from the use of high-pressure synthetic methods, which typically require gigapascals of applied pressure. We report that rhenium diboride (ReB2), synthesized in bulk quantities via arc-melting under ambient pressure, rivals materials produced with high-pressure methods. Microindentation measurements on ReB2 indicated an average hardness of 4...
The possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. The results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. On the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...
Abstract The paper deals with the study of rhenium recovery by AMR anionite from model high-acidic sulfuric solution as well its desorption ammonia in column experiments. Total dynamic exchange capacity was calculated. Experimental data were processed using Thomas, Yoon-Nelson and Bed Depth Service Time models, basic parameters It found that total calculated Thomas fit closest to experimental v...
