Abstract: In the present study, we report the synthesis of two different Kegging-type polyoxometalates (POMs), ammonium heptamolybdate (AHM) and phosphotungstic acid (PWA), loaded hydrogel beads formed from chitosan (Chi), chitosan/methylcellulose (Chi/MC) and chitosan/ gelatin (Chi/Gel). The addition of negatively charged POMs results in cross-linking between positively charged chitosan chains through electrostatic attraction. Fourier transform infrared spectroscopy, scanning electron microscopy, and thermal gravimetri… Show more
