Removal of Chromium (VI) from aqueous solution using chitosan - Starch blend

Author(s): S. Ramasubramaniam, C. Govindarajan, T.Gomathi2, and P. N. Sudha

The removal of Cr (VI) ions from aqueous solutions has been investigated using chitosan/Starch blend under different experimental conditions of initial chromium concentration, adsorbent dose and pH. The adsorption efficiency has been explained in terms of Langmuir and Freundlich equations. The results have revealed that the adsorption of Cr (VI) onto chitosan/Starch blend, which were found to well fit by the Freundlich isotherm. The result indicates that under the optimum conditions, the maximum adsorption comply that the chitosan/Starch blends is an effective adsorbent for chromium
