Summary
Adsorption isotherms for the adsorption of chromium onZoogloea ramigera are developed. The rates were affected by the pH and temperature of adsorption medium. The biomass ofZ. ramigera at pH 2.0 where the optimum pH for biosorption lies exhibited the highest chromium adsorptive uptake capacity. In general, higher adsorptive uptake was observed at 25°C than 35°C and 45°C.
