Biosorption of chromium(III) by Sargassum sp biomass
(Univ Catolica De ValparaisoValparaisoChile, 2002)
Reduction of Chromium from Al(2)O(3)-CaO-SiO(2)-CrOx Slags by Carbon Dissolved in Liquid Iron
(IRON STEEL INST JAPAN KEIDANREN KAIKAN, 2011)
The goal of this work is to investigate the reduction of chromium from a quaternary slag by carbon dissolved in liquid steel. Laboratory scale experiments were conducted to study the reduction of chromium oxides in the ...
Disturbance response indicators of Impatiens walleriana exposed to benzene and chromium
(2017-08-03)
The purpose of this study was to evaluate the remediation potential and disturbance response indicators of Impatiens walleriana exposed to benzene and chromium. Numerous studies over the years have found abundant evidence ...
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 ...

Bioremediation of chromium contaminated soils by Actinomycetes: Mechanisms iInvolved
(Nova Science Publishers, 2011)
In natural water and subsurface soils chromium occurs in two major oxidation states: III and VI. Cr(VI) is approximately 1,000-fold more cytotoxic and mutagenic than Cr(III). As the application of Cr is extensive in several ...
