Background: Excessive phosphorus is the primary nutrient causing water eutrophication. It is of major practical significance to remove pollutants by membrane filtration while adsorbing phosphorus. Methods: In this study, Zr(OH)(4)-PVDF organic/inorganic nanocomposite membrane was formed by in-situ formation of Zr(OH)(4) nanoparticles from ZrOCl2 precursor by sodium hydroxide solution during non solvent induced phase separation process. Significant Findings: The Zr doping in the in-situ grown films is more uniform, and phosphate could be selectively and quickly adsorbed after the decoration of zirconium, and good adsorption capacity was realized as high as 58.67 mg g(-1). At the same time, this Zr(OH)(4) decorated composite membrane had excellent filtration performance, which could effectively remove organic pollutants, such as dyes. This novel organic/inorganic nanocomposite membrane with Zr(OH)(4) nanoparticles in-situ decoration exhibited high adsorption capacity, fast adsorption kinetics and good repeatability, and some water soluble pollutants such as dyes could be filtered successfully. All these could provide a promising new strategy for the in-situ fabrication of organic/ inorganic nanocomposite membrane and a new direction for the design of efficient phosphorus removal filter membrane with excellent adsorption performance.
