Abstract
The synthesis of Cu/Al2O3 nanoparticles (NPs) was conducted by the citric acid sol–gel technique. We used the synthesized NPs to enhance PVC membranes and create PVC-Cu/Al2O3 nanocomposite membranes. The quantities of NPs utilized were 0, 0.5, 1, 1.5, and 2 wt.% of solid phase. The point of this study was to look into how PVC-Cu/Al2O3 membranes can be used to remove natural organic matter (NOM) from polluted water in submerged membrane systems. The membranes treated with NPs exhibited increased porosity, improved hydrophilicity, and smoother surface. Results revealed that the incorporation of 1 wt.% NPs into PVC (PVC-CA1) demonstrated the highest degree of hydrophilicity and porosity. Moreover, PVC-CA1 exhibited an increased number of pores, with larger pores present on the top surface and larger macrovoids on the cross-sectional surface. The PVC-CA1 exhibited the highest flux recovery ratio (FRR) and highest rejection rate for HA, with values of 82.6% and 92.6%, respectively. PVC-CA1, which had an irreversible fouling ratio (IFR) of 17.3%, demonstrated the greatest resistance to fouling. Generally, incorporation of NPs into PVC resulted in increased hydrophilicity, enhanced porosity, uniform dispersion, smoother surface characteristics, and consequently improved antifouling properties. Furthermore, among the fabricated membranes, PVC-CA1 had the most favorable antifouling performance.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
