Abstract Synthesis of ferrate using NaOCl and Fe(OH) 3 from electrolysis used iron, its application for metanil yellow degradation had been done. The was conducted iron zink plates at anode cathode electrodes, respectively, Na 2 SO 4 electrolyte. dissolved ion the then made alkaline NaOH pellet soaked to solution form (FeO -). it compared with other oxidators such as permananate, hydrogen perox...

preparation and uses of quinaldinium dichromate and its polymeric analogue poly (2- vinylquinolinium) dichromate as the new monomeric and polymeric oxochromium-amine complex reagents for oxidizing variousorganic compounds, with emphasis on the latter, are described

Hexavalent chromium (Cr [VI]) genotoxicity was studied using fish micronucleus analysis in peripheral blood erythrocytes from Pimephales promelas, the fathead minnow. Forty-five- to 60-d-old fish were used to assess the spontaneous level of genotoxic damage. The genotoxic effect of Cr (VI) obtained from potassium dichromate (K2Cr2O7) in tests performed for 7-, 14-, and 21-d exposure periods was...

The ability of Bacillus sp. MRKV isolated from tannery effluent which shows resistant towards hexavalent chromium potassium dichromate (K2Cr2O7) was evaluated in this study. The bacterial strain was assayed for its reducing ability towards K2Cr2O7. The study revealed that the isolated strain has the ability to reduce the hexavalent chromium and the optimal conditions required for the chromium r...

In the crystal structure of the title compound, (C(3)H(5)N(2))(NH(4))[Cr(2)O(7)], the anions and cations are linked through N-H⋯O hydrogen bonds, resulting in a three-dimensional structure which contains three kinds of layers parallel to (001). One layer contains imidazole cations, the other two layers the ammonium cations and dichromate anions. The dichromate anion has an eclipsed conformation...

Agricultural by-products are generally poor adsorbents of anions in solution. Therefore, modification of the by-product could enhance its anion exchange capabilities. The objective of this study was to increase the anion exchange properties of the agricultural by-product, soybean hulls, by chemical modification. Soybean hulls were quaternized with the quaternizing agent, N-(3-chloro-2hydroxypro...
