Cr(VI) and Cr(III) removal from aqueous solution by raw and modified lignocellulosic materials: a review
(Elsevier Science, 2010-08)
In aqueous systems, chromium usually exists in both trivalent and hexavalent oxidation states, being Cr(VI) of particular importance and concern due to its great toxicity. Industrial sources of Cr(VI) are leather tanning, ...
Biosorption of Cr(III) using in natura and chemically treated tropical peats
(Elsevier B.V., 2009-04-30)
The physicochemical characteristics of three Brazilian pears were investigated using elemental analysis, scanning electron microscopy (SEM), X-ray diffractometry (XRD) and studies of Cr(III) biosorption based on adsorption ...

γ-Al2O3-supported XMo6 Anderson Heteropolyoxomolybdates: Adsorption Studies for X = TeVI, AlIII, CoIII, CrIII and NiII by DR Spectroscopy and TPR Analysis
(SAGE Publications, 2000-09-20)
The support–overlayer adsorptive interactions, generated when solutions of Anderson heteropolyoxomolybdates were supported as a monolayer on γ-Al2O3 by means of the equilibrium adsorption method, were studied by XRD analysis, ...

Removal of chromium(VI) and chromium(III) from aqueous solution by grainless stalk of corn
(TAYLOR & FRANCIS INC, 2008)
Grainless stalk of corn (GLSC) was tested for removal of Cr(VI) and Cr(III) from aqueous solution at different pH, contact time, temperature, and chromium/adsorbent ratio. The results show that the optimum pH for removal ...
