The biosorption of rhodamine-B from aqueous solution using crosslinked alginate beads was studied by contact method at fixed pH -3 and room temperature (28 +/- 0.2 degrees C). Both the Freundlich and Langmuir isotherm models could describe the adsorption equilibrium of the rhodamine-B onto crosslinked alginate beads. The influence of various experimental parameters such as pH, temperature, effect of concentration and time were evaluated. It was observed that the adsorption capacity of rhodamine-B onto alginate beads decreased with increase in pH and temperature above room temperature.
