- W2243357856 abstract "The existent of pharmaceutical drugs in our aquatic media is a preeminent burden for the environment effect including health fitness issues. The presence of tiny amount of organic and inorganic pharmaceutical drugs including hormones, birth control pills, NSAID, antibodies can causes a huge destruction for our living entity now a days. According to the report of WHO (World Health Organization), it is a matter of concern about the alarming existence of pharmaceutical drugs in our daily water supply systems because of these small portion of Pharmaceutical activated compound can cause enormous health effect for both animals and human being. The photocatalytic degradation of Ibuprofen and cetirizine has been chosen according to their large scale presence with waste water and also creating a benchmark with our conventional and nonconventional treatment processes of our waste water treatment plants to obtain pristine water. Even though our meticulous environmental regulation policy, Ibuprofen and Cetirizine both are vastly used by large portion of community in our society and they are major pharmaceutical contaminant of WWTP (waste water treatment plant) for their enormous uses by human being. TiO2, ZnO and several clay nanopowder with photocatalytic compounds are familiar as photocatalyst and their uses under UV light generator can able to degrade both pharmaceutical drugs. Three different types of TiO2 components (Anatase, Rutile and mixture of Anatease and Rutile) were used to determine the best efficient material among photocatalyst chemical nanopowder. ZnO and montmorillonite clay particles were tested for further verification of photocatalytic characteristics. The entire experiment was accomplished by batch reaction under several operating parameters consideration such as changing pH values, time and concentration. All parameters have very important influence on ibuprofen and cetirizine degradation was verified. Recently many efforts have been made to increase the efficiency of photocatalytic materials.By addition of MWCNT (Multi Walled Carbon Nano Tube) with photocatalyst nano powder can increase the photocatalytic efficiency by increasing recombination time was demonstrated here after examination. The entire goal of this thesis was to develop a suitable, sustainable and efficient hybrid nanofiber composite also successfully investigated. Using photocatalytic nanopowders to degrade the PhACs (Pharmaceutical Active Compounds) in WWTP are not very easy to separate after execution. Therefore, the idea of hybrid nanofibers was fabricated here to get remedy from separation problem. Hybrid nanofibers assembled by PAN (Polyacrylonitrile)/TiO2 where TiO2 were immobilized over electrospun PAN nanofibers. The nanofiber has been fabricated appropriately with electrospinning process by using N, N-dimethyl formamide (DMF), PAN and tetrabutyl titanate [Ti(OBu)4] sol-gel composites. TiO2 immobilized on PAN nanofiber after implementing hydrothermal process. The fabricated hybrid nanofibers were scrutinized with different characterization tools such as X-ray diffraction, field emission scanning electron microscopy, thermo gravimetric analysis and energy dispersive X-ray (EDX) spectroscopy. The outcome of fiber analysis represents the flexibility and large surface area of the hybrid nanofibers. The as-fabricated nanofibers were tested with ibuprofen solution under UV light irradiation. Impressive performances by fabricated nanofibers were examined for ibuprofen degradation after several minutes’ photocatalytic reaction." @default.
