The Tamarindus indica, a plant based waste material was investigated for biosorption of chromium from industrial waste water. The various parameters were evaluated to know the effects on biosorption. The experiments were conducted in batch process. The maximum contact time obtained was 50 min, dosage 1.2gm, metal on concentration 1mg/l and pH 5. The data estimated more suitable to Langmuir model than Freundlich model. The kinetic data well correlated to second order. The thermodynamic parameters were also evaluated. The results revealed that tamarind fruit shell powder (Tamarindus indica) was favourable for biosorption of chromium from waste water. The maximum removal of chromium was 82%.
