DOI: 10.1016/j.cej.2017.04.123

Abstract: Abstract This paper presents ammonia-enhanced oxidation of flumequine (FLU), a representative fluoroquinolone antibiotic, by ferrate(VI) (FeVIO42−, Fe(VI)). The second-order rate constants (k) without ammonia were 9.34 ± 1.04 and 1.16 ± 0.04 M−1 s−1 at pH 8.0 and 9.0, respectively. These… read more here.

DOI: 10.1039/d5cc03102h

Abstract: Aluminum (Al) doping in sodium manganese hexa-cyano-ferrate (NMHCF) stabilizes the cubic phase and suppresses multiphase formation. Doping reduces the particle size (∼0.35 μm), catalyzing the rate kinetics. Further Al-doping promotes aluminum-oxy-fluoride formation at the cathode… read more here.
