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, ...
Adsorption of Cr(VI) from aqueous solution by hydrous zirconium oxide
(ELSEVIER SCIENCE BV, 2010)
A type of ZrO(2)center dot nH(2)O Was synthesized and its Cr(VI) removal potential was investigated in this study. The kinetic study, adsorption isotherm, pH effect, thermodynamic study and desorption were examined in batch ...
Adsorption of chromium(VI) ions on Brazilian smectite: Effect of contact time, pH, concentration, and calorimetric investigation
(Elsevier Science BvAmsterdamHolanda, 2010)
ZrO2 thin film grafted on silica gel surface: Preparation and Cr(VI) adsorption property
(Soc Brasileira QuimicaSao PauloBrasil, 2002)
Chromium (VI) removal from water by means of adsorption-reduction at the surface of amino-functionalized MCM-41 sorbents
(Elsevier Inc, 2016-10)
A first study that demonstrates the capability of the amino-functionalized MCM-41 sorbents to reduce Cr(VI) to the less toxic trivalent state is presented. To achieve this aim two mesoporous ordered silica with MCM-41 pores ...
Potential biopolymer adsorbent functionalized with Fe3O4 nanoparticles for the removal of Cr(VI) from aqueous solution
(2022)
In the present study, an adsorbent with a synergistic effect was developed from chitosan (CS) and Fe3O4 nanoparticles (Fe3O4 Nps) to remove Cr(VI) from aqueous solutions. The Fe3O4 Nps were synthesized by co-precipitation ...
