TAILIEUCHUNG - Fabrication of cellulose based chitosan coating adsorbents for capture to Cadmium (II) and Zinc (ii)
Cellulose fiberous adsorbent (CCCF) was prepared from sugacane agasse by coating chitosan on the fiber surface. The chitosan layer coated on the cellulose fiber enhanced adsorption to Cd2+ and Zinc2+ . High efficency of the CCCF of removal % for the Cd (II) and Zn (II) was with % and %, respectively and the adsorption capacity was mg/g. | Vietnam Journal of Science and Technology 55 (4C) (2017) 224-230 FABRICATION OF CELLULOSE-BASED CHITOSAN COATING ADSORBENTS FOR CAPTURE TO CADMIUM (II) AND ZINC (II) Truong Thi Cam Trang1, *, Nguyen Trong Quan1, Sadaatsu Kaneda2, Lisa Nakajima2, Takaomi Kobayashi2 1 Faculty of Environmental Science - University of Science, VNU-HCMC, 227 Nguyen Van Cu, Ward 4, District 5, Ho Chi Minh City, Viet Nam 2 Department of Material Science and Technology, Nagaoka University of Technology, 1603-1, Kamitomioka Nagaoka, Niigata 940-2188, Japan * Email: ttctrang@ Received: 30 June 2017; Accepted for publication: 16 October 2017 ABSTRACT Cellulose fiberous adsorbent (CCCF) was prepared from sugacane agasse by coating chitosan on the fiber surface.

INTRODUCTION Cellulose ((C6H10O5)n) is the most abundant organic polymer in nature and polysaccharide consisting of linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Therefore, there were many reports on uses of cellulose in the chemical modification to cellulose derivatives. For example, consisted of the OH group is easy to chemically modify. The resulting decrease in water absorption capacity leads to an increase in the durability and stability of the cellulose. Thus, such treatment steps was conducted in order to increase the chemical activity and physical strength of the product [1]. On the other hand, chitosan is secondary abundant polymer often seen as a white powder and has interesting properties of biocompatibility, biodegradability and non-toxicity. Among them, it was used well-known that complex associations with metal ion through specific interactions was .
