Description Use of commercially available levigated alumina GRM-1909 for adsorption of Hexavalent chromium is investigated. In this study,
the adsorption of Cr(VI) was carried out in a batch mode and rate of adsorption was evaluated at varying conditions viz. pH,
adsorbent dose, initial concentration and contact time. The maximum removal of Cr(VI) (98%) was observed at pH 4 with an
adsorbent dose 1 gm/100 ml and chromium concentration of 10 mg/l. The adsorption study revealed that pH and adsorbent dose
play significant roles towards Cr(VI) adsorption. Langmuir and Freundlich adsorption isotherm models were applied. The
Langmuir isotherm fitted the equilibrium adsorption data better with a correlation coefficient of R2 = 0.971. The present study
reveals that the commercially available levigated alumina can be an ideal candidate for the removal of chromium (VI) metal ions
from waste water.
