Sequential spectrophotometric determination of chromium(III) and chromium(VI) using flow injection analysis
(1985-12-01)
A flow injection analysis (FIA) procedure for the speciation of Cr(III) and Cr(VI) using the 1,5-diphenylcarbazide (DPC) method is presented. As Cr(III) does not interfere in the Cr(VI) - DPC reaction, both Cr(VI) and total ...
Radiometric and spectrophotometric studies of the behavior of chromium(VI) oxide in concentrated perchloric acid
(R Oldenbourg VerlagMunchenAlemanha, 1997)
Factors affecting chromium(VI) reduction by Thiobacillus ferrooxidans
(Elsevier Science Sa, 2001-02)
The ability of Thiobacillus ferrooxidans cultures to reduce chromium(VI) to chromium(III) was evaluated under different conditions. In T. ferrooxidans cultures with sulphur as energy source, the capacity for chromium(VI) ...

Adsorption of chromium(VI) by titanium(IV) oxide coated on a silica gel surface
(Royal Soc Chemistry, 1991-03-01)
Titanium(IV) oxide, coated on the surface of silica gel (surface area, 308 m2 g-1; amount of Ti(IV) per gram of modified silica gel, 1.8 x 10(-3) mol), was used to adsorb CrO4(2-) ions from acidic solutions. The exchange ...

Análisis de toxicidad de metales contaminantes sobre el crecimiento de Escherichia coli: efecto de cromo, plomo y cadmio en solución
(2014-10-14)
El riesgo asociado a la contaminación de suelos y aguas subterráneas con cromo (VI) derivado de activi-dades industriales es elevado. La reducción microbiana de cromo (VI) constituye una estrategia limpia en la preservación ...
