ABSTRACT
The present study focuses on utilising gamma irradiation to prepare Poly (PVP/acrylamide/glycerol/bentonite clay) nanocomposite film poly(PVP/AAm/Glyc/BNTN) with composition (40/60/5/0.25 wt %) at different doses of 10, 20, 30 and,40 kGy. The FTIR analysis shows the successful preparation and modification of the different irradiated poly(PVP/AAm/Glyc/BNTN) nanocomposite film at different doses. The film irradiated at 40 kGy is a stable film that has higher water resistance properties than other prepared films as shown in the swelling study. The bentonite nano clay was found to be homogeneously and well distributed in the surface of the nanocomposite film modified at 40 kGy, which led to the chemical stability of the synthesised poly(PVP/AAm/Glyc/BNTN) with composition (40/60/5/0.25 wt %) as shown in the swelling study, and field emission scan electron microscope (FESEM). Also, the bentonite nanoparticles have an average particle size of 76.5 nm.
The impacts of the different factors which include pH, contact time (h.), and temperature (k) on the uptake of Acid red 37 (AR 37) dye from its aqueous solution were investigated. The Langmuir model was established as the suitable model for this work and the uptake of AR 37 dye was designated by the pseudo-second-order kinetic model to be spontaneous and endothermic. Furthermore, the adsorption capacity was enhanced with the temperature and time and reduced with increasing the pH of the dye solution. The maximum adsorption capacity of Poly(PVP/AAm/Glyc/BNTN) samples to the anionic AR 37 dye was found to be 136.13 mg/g at pH 4, contact time 8 hrs, and amount of adsorbent 0.3 g/100 ml of the dye solution.
