There is a great demand to develop different techniques for the continuous removal, immobilization, and remediation of metallic ions from contaminated water. Human contamination by could even occur ingestion seafood causing carcinogenic mutagenic activities. In this study, nanofibrous membrane poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) produced electrospinning technique coated...

The oxidation of D-lactobionic acid by Cr(VI) yields the 2-ketoaldobionic acid and Cr(3+) as final products when a 20-times or higher excess of the aldobionic acid over Cr(VI) is used. The redox reaction takes place through a complex multistep mechanism, which involves the formation of intermediate Cr(IV) and Cr(V) species. Cr(IV) reacts with lactobionic acid much faster than Cr(V) and Cr(VI) d...

In connection with the production of 46.2 min Mn via the Cr(d, n)-process, several separation techniques such as ion exchange chromatography, solid phase extraction, liquid–liquid extraction and co-precipitation have been investigated; the aim was to separate no-carrier-added radiomanganese from the bulk target chromium. Among the separation systems ∗MnII/CrIII , ∗MnII/CrVI and ∗MnIV/CrVI, the ...

results the level of gsh significantly decreased. in contrast, the plasma level of mda significantly increased in a dose dependent manner in crvi-treated rats, when compared to control animals. simv had no effect on the biochemical parameters when compared to control rats, but significantly increased gsh concentration and decreased mda level in crvi-treated rats. materials and methods sixty-fou...

The aim of the present study was to provide new knowledge regarding effect non-expansive inert material addition on anionic pollutant removal efficiency in Fe0-H2O system. Non-disturbed batch experiments and continuous-flow-through column tests were conducted using CrVI as a redox–active contaminant three different systems: “Fe0 + sand”, only” ”sand only”. Both experimental procedures have adva...
