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.
