Photo-active trans-3-(4-pyridyl)acrylic acid (PYA) modified chitosan (CSPA) was synthesized with different functionalization degrees and extensively examined using Fourier transform infrared spectra (FTIR), 1H and 13C nuclear magnetic resonance (NMR) in order to elucidate the chemical structure of the modified biopolymer. The modified CSPA with various(More)
In this work, uranyl complex with Schiff base derived from condensation of p-aminostyrene and salicyaldehyde (HASS) was synthesized. Both ligand and uranyl complex were characterized using elemental analysis, FTIR, (1)H and (13)C NMR spectra. The complex was then copolymerized with styrene and divinylbenzene cross-linker using potassium persulfate free(More)
In this article photo-crosslinkablestyryl-pyridine modified alginate (ASP-Alg) was prepared and entirely investigated utilizing different instrumental techniques such as Elemental analysis, Fourier transform infrared (FTIR),(13)C and (1)H nuclear magnetic resonance (NMR), ultraviolet-visible light (UV-vis), X-ray diffraction (XRD) spectra and scanning(More)
