✦ Synopsis

The sorption of chromium (Cr+6) was investigated for 50 day starved and fresh cells in the presence of sulfate ion as a competing ion at three pH values (pH 6.0.7.5 and 9.0). The chromium distribution in the subcellular components was also determined by conducting cell fractionation. Although a previous study showed that cells which had been starved for 50 days prior to being exposed to a chromium containing solution sorbed lo-15% more chromium than did fresh cells (Kong ef al., 1992a). this study demonstrated that such cells did not sorb more chromium in the presence of sulfate ion.
