Synthesis and Characterization of Nanocomposites of Biodegradable Polymers Based on Chitin, Alginic, Sr, SiO2 and Graphene Oxide Nanoparticles to Remove Some Colored Contaminants
Biodegradable polymers are not considered an environmental hazard to the health of living organisms. This research used a nanocomposite adsorbent based on natural (biodegradable) polymer materials. This nanocomposite was made from natural chitin and alginate monomers with graphene oxide, silicon oxide nanoparticles, and strontium metal nanoparticles under reflux and ultrasonic. FTIR, XRD, SEM, TEM, EDX, Zeta potential, and TGA analyses were performed to identify and characterize the synthesized materials. Methylene blue dye was used as a contaminant to remove from the aqueous media. The removal ability of the synthesized adsorbent from aqueous media was studied using methylene blue as an organic pollutant. The maximum removal percentage of methylene blue by the synthesized adsorbent was 98.5 %. The results indicated that the synthesized nanocomposite is an acceptable adsorbent for removing methylene blue dye from aqueous media.</em>
