A novel adsorbent was prepared by using root of Neem Tree. The powder produced was characterized on the basis of surface morphology and specific surface area (854.52m2/g). Batch experiments were carried out to study the removal of Cr (VI) from synthetically produced chromium solution in laboratory. Three parameters were varied i.e. adsorbent dose, contact time and initial metal concentration. The data fitted well in Langmuir Isotherm with monolayer capacity of 20.36. The maximum removal efficiency was at lower concentrations. 5g/L of adsorbent dose was found optimum. Kinetics of removal was fast as equilibrium was reached in 60 min. Thus Neem Root adsorbent proves to be efficient and low cost for the removal of hexavalent chromium.
