PEREZ GARCIA, Pablo Marcelo; IBANEZ-CALERO, Sandra L.  y  ESCALERA VASQUEZ, Ramiro. DEGRADATION OF SYNTHETIC ORGANIC DYES IN SOLUTION BY FERRATE - HYPOCHLORITE OR CALCIUM HYPOCHLORITE. Inv. y Des. [online]. 2017, vol.1, n.17, pp. 43-53. ISSN 2518-4431.

This study investigated the use of ferrate - hypochlorite solution or solid Ca(OCl)2 as treatment options to remove color and COD from solutions of the synthetic organic dyes: Reactive blue 19, Allura red and Reactive black 5. It was found that doses around 1000 ppmCa(OCl)2 had color removal efficienciesaround 90 % for all the dyes after 15 minutes reaction time; this treatment had a COD removal efficiency of 97 % forazo dyeAllura red. The ferrate - hypochlorite (0.06 mM - <400 ppm) treatment resulted in a 50% color removal for Reactive blue 19 dye after 1 hour reaction time. The COD removal of Reactive blue 19 dye was improved from 40% to 84% when the ferrate - hypochlorite solution was used.

Palabras clave : Ferrate; Synthetic Organic Dyes; Hipochlorite; COD Removal.
