Abstract

The expansion of urbanisation, industrialisation, and population has led to water pollution due to severe contamination by toxic pollutants, increasing the demand for pure water. Arenic poisoning of water is considered as the worst chemical poisoning due to its hazaedous effect on the environment. The present study combines nanotechnology and membrane technology to overcome water scarcity issues and removal of the arsenic from the contaminated water. Polyethersulfone (PES) hollow fiber membranes, with and without nanoparticles (NPs), were fabricated through the dry-wet spinning process and used for ultrafiltration studies. Physicochemical characterisation confirmed the successful synthesis of bare nanoparticles, and further, membranes were characterised and analysed by various studies. The study demonstrated significant improvements in As(V) removal efficiency and water flux. The optimised membrane achieved a removal rate of 79.23% and the highest flux of 26.7 L/m²/h compared to the pristine membrane, which had a 65% removal rate and a flux of 18 L/m²/h, emphasising potential for water purification applications.
