Development of in situ synthesis of silver polysulfone membrane for water separation

Water treatment using membrane filtration is one of the common methods that can generate higher amount of quality water in future. However, polymer blending method via ex-situ synthesis method shows some weaknesses on membrane modification such as membrane prone to fouling and hydrophobic. In this p...

However, polymer blending method via ex-situ synthesis method shows some weaknesses on membrane modification such as membrane prone to fouling and hydrophobic. In this present work, the development of in-situ synthesis of silver (Ag)/polysulfone (PSf) membrane was carried out for water separation purposes. The effect of different types of silver on membrane performance, the effect of silver precursor and the effect of in-situ synthesis of silver in PSf membrane has been investigated. The Ag/precursor dope solution thermodynamic stability was evaluated via ternary phase diagram. The membrane was characterized in term of morphology, existence of element, surface roughness, porosity and hydrophilicity. Then, the membrane performance was evaluated in respect to water permeability, water quality assessment, fouling, and antibacterial properties using E.coli. The performance of AgN03 was highly influences by PSf/alkali characterization. The result was compared with PSf/ AgzO membrane as the in-situ synthesis of AgN03 with alkali precursor was reacted as AgzO behavior. PSf/AgN03/LiOH membrane surface roughness increased up to 58 % causing higher surface area of the membrane. Then, water permeation flux rate increased up to 21 % and water quality assessment reached 86 % using lake water. In addition, high molecular weight of alkali reacts with AgN03 effectively and resulted on low flux reduction and high antibacterial properties as compared to regular polymer blending method of silver on PSfmembrane. The silver stability on the membrane surface also has been improved significantly. Thus, in-situ synthesis of silver has potential to be used as a method in membrane fabrication as it enhances membrane performance for water separation. 2018-08 Thesis http://eprints.uthm.edu.my/236/ http://eprints.uthm.edu.my/236/1/24p%20AZLINNORAZIA%20BINTI%20AHMAD.pdf text en public http://eprints.uthm.edu.my/236/2/AZLINNORAZIA%20BINTI%20AHMAD%20COPYRIGHT%20DECLARATION.pdf text en staffonly http://eprints.uthm.edu.my/236/3/AZLINNORAZIA%20BINTI%20AHMAD%20WATERMARK.pdf text en validuser mphil masters Universiti Tun Hussein Onn Malaysia Faculty of Mechanical and Manufacturing Engineering
