AbstractThe Influence of electron beam on behaviors of high density polyethylene/poly(ethylene glycol)/organoclay nanocomposites has been studied. Nanocomposite compounds were prepared by melt intercalation method. X-ray diffraction (XRD) and transition electron microscopy (TEM) revealed the combination of nanocomposite morphology. Thermal and mechanical properties of nanocomposites were studied by using Thermogravimetric analysis (TGA), Young's modulus, tensile strength and hardness tests. The results show that at 500 KGy dose of irradiation the Young’s modulus and tensile strength values have been enhanced in comparison with pure blend by cross-linking and the surface hardness of samples raises by increasing the clay content The samples with the clay content of 5 wt% in the matrix with 500KGy dose of irradiation have shown satisfactory thermal resistance.The irradiation at high levels has degraded the nanocomposites and an optimum dose must be employed to enhance their properties. The presence of poly(ethylene glycol) as a compatibilizer has improved the dispersion of clay layers into the matrix and has enhanced the mechanical properties and thermal resistance of nanocomposites. The presence of the clay in the matrix has increased the adsorption amount of xylene and toluene into the bulk of nanocomposites and the irradiation has decreased this capacity by the dose level.

Chitosan-Silica blended membranes were an attractive choice for the purification process because their porous size and morphology provide higher selectivity. In this study, the synthesis and characterization of chitosan-silica membranes were carried out with a mass variation of Poly Ethylene Glycol (PEG): 0,5; 2,5; 5 grams, Poly Vinyl Alcohol (PVA): 1, 2, 3 grams; and pressure 1, 2, 3 bars for the hotel wastewater treatment. The purpose of this study was to determine the characterization of chitosan-silica membranes obtained by SEM and tensile strength, and to determine the performance of membrane against the flux and rejection test with the effect of a mixture of PEG and PVA mass using raw materials in form of chitosan-silica. Tensile strength analysis showed that membrane with the highest tensile strength was 19,14 Mpa for PEG and 13,7 Mpa for PVA. The SEM test results showed a relatively small pore size of PEG 0,5 gram (0,061 μm) and PVA 2 grams (0,0284 μm). Flux and rejection results showed that membrane with 2,5 grams composition of PEG was the most effective in performance with the flux 18,19 L/m2.h and rejection elimination of BOD (50,76%), COD (46,09%) and TSS (48,00%). On the other hand, flux results showed that membrane with 3 grams composition of PVA was the most effective with the flux 20,13 L/m2.h and rejection elimination of BOD (62,84%), COD (64,73%) and TSS (38,40%). The characteristics of permeability, selectivity, and membrane pore statistics show that the silica membrane is an ultrafiltration membrane.
