Synthesis and Characterization of Crosslinked Cellulose Schiff base as a Novel Bio Based Polymer Ligand

Abstract

Cellulose is recognized as the most abundant biopolymer in nature offer wide chance to be<br>used for superior applications such as water purification [1,2]. It is natural, renewable, environmentally<br>friendly, efficient and cost-effective, sustainable, bio–degradable and derived also<br>easily from plant sources [3]. In this context, fully biobased and crosslinked adsorbent polymer<br>Schiff base was prepared by using oxidation reaction of extracted cellulose biopolymer.<br>A safe crosslinked cellulose dialdehyde -CCDA- was synthesized through epichlorohydrin<br>and sodium metaperiodate -NaIO4- followed by Schiff base formation with pphenylenediamine<br>[Fig. 1]. Crosslinking, oxidation and Schiff base formation of the extracted<br>cellulose was confirmed by using FTIR spectrum. The index bonds of crosslinked cellulose<br>-CC-, CCDA and the crosslinked cellulose Schiff base -CCSch- were appeared at about 3419,<br>1727 and 1607 cm-1 respectively. The prepared imine bands and microstructure of the synthesized<br>product was investigated from EDS and SEM analyses.<br>-Project code 3/47733-
