Özet:

 The release of harmful and toxic pollutants such as synthetic organicinorganic substances and metals into water resources due to increasing agricultural and industrial activities in recent times has been creating increasing public concern.Arsenic, one of these toxic and harmful substances, poses a significant threat to water resources in some regions. Removal of arsenic from drinking water is important worldwide because arsenic is toxic, carcinogenic and ubiquitous. Therefore, it is necessary to develop simple, less costly and environmentally friendly techniques for arsenic removal from drinking water. Strengthening membranes with nanomaterials has recently become a widely used method. In addition, the use of thin-film nanocomposite hybrid materials prepared by selecting and adding nano-scale inorganic additives has added a new dimension to membrane technology. In this study, nanomaterial supported membranes with high permeability and rejection rate were developed by coating the polysulfone solution modified with Fe3O4 nanoparticles on the porous support sheet material. The prepared nanocomposite materials and membranes were characterized using scanning electron microscopy SEM, atomic force microscopy AFM, X-ray photoelectron spectrophotometer XPS and contact angle CA techniques.Membrane performance studies have been carried out with pure water permeability and arsenic rejection studies and prepared PSf-based including at different GOFe3O4 ratios in the nanocomposites membranes have been observed high performance and achieved 95 arsenic rejection rate.

 Son zamanlarda giderek artan tarımsal ve endüstriyel faaliyetler nedeniyle sentetik organikinorganik maddeler ve metaller gibi zararlı ve zehirli kirleticilerin su kaynaklarına salınması kamuoyunda giderek artan bir endişe yaratmaktadır. Bu zehirli ve zararlı maddelerden arsenik, bazı bölgelerde su kaynakları için önemli bir tehdit oluşturmaktadır. Arsenik zehirli, kanserojen ve her yerde bulunduğundan dünya çapında içme suyundan arseniğin giderimi önemlidir. Bu nedenle, içme suyundan arsenik giderimi için basit, daha az maliyetli ve çevre dostu tekniklerin geliştirilmesi gerekmektedir. Nanomalzemeler ile membranların güçlendirilmesi son zamanlarda yaygın olarak kullanılan bir yöntem haline gelmiştir. Ayrıca nano ölçekli inorganik katkı maddelerinin seçilip eklenmesiyle hazırlanan ince film nanokompozit hibrit malzemelerin kullanılması membran teknolojisine yeni bir boyut kazandırmıştır. Bu çalışmada, Fe3O4 nanoparçacıkları ile modifiye edilmiş grafen oksit GO katkılı polisülfon çözeltisinin gözenekli destek malzemesi üzerine kaplanması ile yüksek geçirgenlik ve reddetme oranına sahip nanomalzeme destekli membranlar geliştirilmiştir. Hazırlanan nanokompozit malzemeler ve membranlar taramalı elektron mikroskobu SEM, atomik kuvvet mikroskobu AFM, X-ışını fotoelektron spekrofotometresi XPS ve temas açısı CA teknikleri kullanılarak karakterize edilmiştir. Membran performans çalışmaları saf su geçirgenliği ve arsenik reddi çalışmaları ile gerçekleştirilmiş ve hazırlanan PSf bazlı nanokompozit membranlarda farklı GOFe3O4 oranlarında dahil olmak üzere yüksek performans gözlemlenmiş ve 95 arsenik reddi oranına ulaşılmıştır.
