摘要：
Adsorption of Cr(VI) by two tannin sorbents is evaluated using radiotracers. Evaluation of the sorption process shows that the Cr(VI) -tannin molecule binding is the principal responsible For chromium adsorption. High sorption capacities were registered for both sorbents at pH 2. For Eucaliptus Saligna Sm sorbent (ETS) sorption capacity is 0.92+/-0.03 mmol/g and for Lysiloma latisiliqua sorbent (LTS) is 3.8+/-0.3 mmol/g. Influence of different ions present in water is examined. High sorption capacity is reported for LTS in sea and tap water samples. It represents 90-94% of adsorption in distillated water.
