TiO2/void/porous Al2O3 shell embedded in polyvinylidene fluoride film for cleaning wastewater
In order to selectively adsorb hydrolyzed polyacryamide (HPAM) and remove oil from oily wastewater, TiO 2 /void/porous Al 2 O 3 shell particles (TVAs) were designed and prepared though hydrolysis and calcination; subsequently, the TVAs were embedded into polyvinylidene fluoride (PVDF) to prepare com...

| description | In order to selectively adsorb hydrolyzed polyacryamide (HPAM) and remove oil from oily wastewater, TiO 2 /void/porous Al 2 O 3 shell particles (TVAs) were designed and prepared though hydrolysis and calcination; subsequently, the TVAs were embedded into polyvinylidene fluoride (PVDF) to prepare composite films (TVAP films). As polymeric supports, TVAP films were employed to immobilize TiO 2 powder. TVAs were characterized using SEM, TEM, FT-IR, BET while TVAP films were characterized by SEM. The results indicate that the particle size of TVAs is mainly distributed between 700 and 800 nm, core-shell structure has been successfully built. The removal rates of TVAP films prepared under the optimum synthesis conditions for oil and HPAM reach 69.70% and 60.20% respectively, performing attractive properties of mass transfer and adsorption. Therefore, TVAP films are desirable as suitable materials to clean oily wastewater. |
