Özet
The present paper focused on synthesizing a polyacrylamide-titanium dioxide (PAA@TiO2) nanocomposite using a cross-linking method with N, N′-methylenebisacrylamide and then using this composite to eliminate crystal violet (CV) dye from water and to characterize the adsorbent by XRD, FT-IR, and SEM-EDX techniques. The characterization revealed that TiO2 nanoparticles dispersed homogeneously within the polymer matrix. The maximum amount of adsorption was about 38.9 mg g−1 under the adsorbent dose of 5 g L−1, 500 mg L−1 CV dye concentration, and pH 6.9. The interaction between the CV molecule and the PAA@TiO2 nanocomposite surface was studied using Monte Carlo (MC) and molecular dynamics (MD) simulations. The negative value of the Eads (− 586.56 kcal mol−1) of the CV molecules onto the PAA@TiO2 nanocomposite surface gives credibility to the experimental results. All obtained results showed that PAA@TiO2 hybrid polymer nanocomposite could be an alternative adsorbent for crystal violet dye removal from wastewater.
