A green approach toward synthesis of largesurface ligands based on cellulose extracted from plant

An original approach for preparing bio-polymer ligands was developed.Two novel bio-polymer ligands were synthesized via oxidation of celluloseextracted (DAC) from safflower plant. Extracted cellulose polymer wascrosslinked and periodate oxidized following to preparation of polycarboxylicacid and Schiff base ligands using sodium chlorite and ethylenediamine, respectively. The physicochemical characterization of thecondensation products was performed using Fourier transform infrared(FTIR) spectra. The index bonds of carboxylated and Schiff based cellulosewere appeared at about 1731 cm-1 and 1649 cm-1, respectively. The crosssectional view of the crosslinked and uncrosslinked products, as absorvedby SEM, showed prous and fibrillose structure for the crosslinked units.
