Role of ferrate VI (K2FeO4) as an iron VI compound in water treatment

abdellatif el maghraoui,
Abstract :
ABSTRACT Iron VI compounds show an incredible progression from being powerful super oxidants and antibacterial; which indeed shows their interest as a green and versatile chemical product in water treatment. This article therefore presents the inactivation efficiencies of these pathogenic microorganisms (E. coli, Missouri Bacteria, Streptococcus, Shigella, Proteus, Pseudomonas sp.) by ferrate (VI) and evaluates their resistant power for the first time against ferrate VI (K2FeO4) of purity > 97% in order to optimize their concentration under specific conditions, as well as to study the effect of the contact time of ferrate VI on the different bacterial strains. 4mg/l, 5mg/l, 5mg/l, 6mg/l, 6mg/l and 6mg/l respectively represent the optimum doses to inhibit these microorganisms within a contact time of 20 minutes at pH = 8. The water purification of the Fez wadi (Fez Morocco) was used as an application to establish our results. Due to their pollution by different indigenous bacteria and their location in the city, the dose of K2FeO4 has been optimized at 12 mg/l.


Banana stem extract was used in the green production and characterization of silver nanoparticles to determine their effectiveness as a possible anticancer drug

Abstract :
Due to their many potential uses and applications in the biomedical sciences, bio-synthesized silver nanoparticles are a fascinating area of interest in the nanobiosciences. Even if several biological components are used in the green synthesis of silver nanoparticles, there is still a great deal of room for advancement in the production of stable and widely useful silver nanoparticles. Despite the various biological uses, silver nanoparticles mostly produced through biological means which have been evaluated as an antibacterial agent. Therefore, the objective of the current work is to highlight the use of biologically produced silver nanoparticles as anti-inflammatory agents. This study is also likely the first to assess the potential of banana stem extract to decrease AgNO3 to Ag-nanoparticles. UV-Vis spectroscopy, DLS, XRD, and zeta potential measurements were used to characterize the nanoparticles, and SEM and TEM were used to examine their morphology. The cytotoxicity of the synthesized nanoparticles and the anti-cancer effects of BSE via inducing apoptosis and its molecular indicators were assessed. This suggests that it could be a cutting-edge, environmentally acceptable method for producing non-toxic, cost-effective silver nanoparticles through biosynthesis.
