Journal ArticleDOI
Removal of Cd(II), Cr(VI), Fe(III) and Ni(II) from aqueous solutions by an E. coli biofilm supported on kaolin
TL;DR: In this paper, the ability of Escherichia coli supported on kaolin to remove Cr(VI), Cd(II), Fe(III) and Ni(II) from aqueous solutions was investigated.
Journal ArticleDOI
Biosorption of Cr(VI) by three different bacterial species supported on granular activated carbon: a comparative study.
TL;DR: Results showed that the biofilms tested are very promising for the removal of Cr(VI) in diluted industrial wastewater, and despite differences in the cell wall structure and composition, the three bacteria exhibit comparable sorption affinities towards chromium, in the open systems studies.
Journal ArticleDOI
Treatment of chromium(VI) solutions in a pilot-scale bioreactor through a biofilm of Arthrobacter viscosus supported on GAC
TL;DR: It was observed that as the initial chromium concentration increases, the uptake increases too, but the removal percentage decreases, with values between 95.20% and 38.28% for the initial concentration of metal.
Journal ArticleDOI
Biosorption potential of dead and living Arthrobacter viscosus biomass in the removal of Cr(VI): Batch and column studies
TL;DR: In this paper, a batch experiment was conducted with dead and living Arthrobacter viscosus biomass for removal of toxic Cr(VI) from aqueous solution in highly acidic pH (pH 1 and 2).
Journal ArticleDOI
Biosorptive performance of an Escherichia coli biofilm supported on zeolite NaY for the removal of Cr(VI), Cd(II), Fe(III) and Ni(II)
TL;DR: In this paper, the ability of a biofilm of Escherichia coli supported on NaY zeolite to biosorb Cr(VI), Cd(II), Fe(III) and Ni(II) was investigated in batch experiments aiming the treatment of wastewater with low metal concentrations.
