Polysulfone/iron oxide nanoparticles ultrafiltration membrane for adsorptive removal of phosphate from aqueous solution

Excessive nutrient contents in water bodies renders eutrophication and causes undesired structural changes to the environment. One of the most straightforward strategies to address eutrophication issue is through the removal of nutrients such as phosphate ions from the water sources. A combination o...
