Preparation of nano selenium particles by water solution phase method from industrial dust
In this study, selenium was recovered from an industrial dust. After the purification process, the researchers were able to prepare selenium micro powder. The objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. The results showed that selenium micronized powder and nano particles had high purity. The obtained nanoparticles were t...

متن کاملCollectorless flotation of Chalcocite by controlling redox potential
Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions. By increasing potentials, on t...
متن کاملIn vitro digestion of selenium from selenium- enriched chicken*
Selenium (Se) is an essential trace element important for several biological functions, such as thyroid hormone metabolism, anti-aging, and antioxidant protection. Even though reports on Se species in different food products are increasing, the scientific knowledge on the bioaccessible amount of Se species from these products is not as well known. In this work, Se-enriched chicken meat was dige...
متن کاملExclusion of selenium from proteins of selenium-tolerant astragalus species.
Protein fractions from three selenium-tolerant and three selenium-sensitive Astragalus species, grown in the presence of [(75)Se]selenate, were analyzed for their selenium content. Though tolerant species are known to accumulate considerably more selenium than do sensitive plants, protein fractions from the three selenium accumulators were found to contain significantly less selenium (0.46 to 0...
