	%X Arthrobacter viscosus biomass was used for Cr(VI)
biosorption. The effect of pH on Cr(VI) reduction and removal from
aqueous solution was studied in the range of 1-4. The Cr(VI) removal
involves both redox reaction and adsorption of metal ions on biomass
surface. The removal rate of Cr(VI) was enhanced by very acid
conditions, while higher solution pH values favored the removal of
total chromium. The best removal efficiency and uptake were
reached at pH 4, 72.5 % and 12.6 mgCr/gbiomass, respectively.
