Abstrakt: The present study involved the preparation of a nano-polymer based on shrimp wastes as a biodegradable chitosan nanoparticle (Cs) incorporated into titanium oxide nanoparticles (TiO 2 ) in an aqueous medium and carried on the specific polymer to form thin films. The spectroscopic properties of chitosan/TiO 2 /Polymer thin films were estimated by transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. The fabricated films were then examined for their potential to eliminate iron (Fe) and chromium (Cr) from solutions. The adsorption efficiency was also evaluated along various contact times. In general, the results illustrated that the heavy metals removal increases with increasing the different ratios of chitosan and TiO 2 nanoparticles incorporated in polymer thin films. Removal efficiency increased with an increase in contact time. More than 70% of Fe and Cr ions were removed in the first 30 min of contact time using different thin films examined. The maximum removal for metal ions after 90 min for the pest thin film (0.08 TiO 2 ) was 97.1 and 88.8% for Fe and Cr, whereas the lowest thin film removal efficiency (PVC) was 29.5 and 8.07% for Fe and Cr, respectively. In conclusion, the fabricated thin film composed of polyvinylidene chloride and chitosan plus 0.08 g titanium oxide nanoparticles had a heavy metal removal capacity three times greater than that of basic polyvinylidene chloride.
