Chemical warfare agents (CWAs) are one of the most toxic compounds. Degradation CWAs using decontamination is few ways to protect human health against harmful effects CWAs. A ferrate (VI)-based potential chemical agent decontaminant was studied for degradation persistent nitrogen mustard (tris(2-chloroethyl)amine, HN3). By optimizing reaction conditions, complete HN3 achieved in 4 min. The prod...

The photocatalytic degradation of dimethyl phthalate (DMP) in aqueous TiO2 suspension under UV illumination has been investigated using oxygen (O2) and ferrate (Fe(VI)) as electron acceptors. The experiments demonstrated that Fe(VI) was a more effective electron acceptor than O2 for scavenging the conduction band electrons from the surface of the catalyst. Some major intermediate products from ...

Mössbauer Spectra, Hexacoordinate Complexes A series of compounds Na3[Fe(CN)5RNH2] * nH 20 where R = -H, -CH3, -C2H5, n-C3H7, n-C4H9 and -CH2C6H5 and RNH2 = C5H5N have been studied by Mössbauer spectroscopy. Quadrupole splitting (A EQ) values vary in a limited range (0.68-0.80 mm/sec) indicating only small distortions in the octahedral geometry of the compounds with the substitution of various ...
