Abstract

Article history: N, N, N-Triethyl ammonium functionalized cross-linked chitosan beads (TEACCB) was prepared by Received 4 December 2015 alkylation of glutaraldehyde cross-linked chitosan beads to remove nitrate from brackish water. Physico- Received in revised form 12 March 2016 chemical characteristics of TEACCB were analyzed using FTIR, SEM, EDAX, TGA, DTA, BET surface area, Accepted 24 March 2016 swelling ratio and pH . The maximum nitrate removal capacity of TEACCB was 2.26 meq/g and is higher zpc Available online 1 April 2016 than other reported chitosan based adsorbents. Nitrate removal ratio in the presence and absence of common anions like chloride and sulphate demonstrated the selectively of TEACCB towards nitrate. The Keywords: kinetic data of nitrate removal fitted well with the pseudo-second-order kinetic model. The thermo- Chitosan dynamic parameters indicated that nitrate removal could be spontaneous and exothermic in nature. Nitrate TEACCB was reused with 100% efficiency after regenerating with 0.05 N HCl. Column study was carried Brackish water out to remove nitrate from brackish water. These results are very significant to develop TEACCB based Column study nitrate removal technology with great efficiency. © 2016 Elsevier Ltd. All rights reserved. 1.
