Abstract
Sulfites can pollute the environment and pose a great risk to human health in daily life, so there is an urgent need to develop efficient and lightweight sulfite detection materials. In this study, metal-organic framework-5-NH2/urushiol/PVP nanofiber composite films were prepared by an electrospinning technique for the fluorescence detection of sulfites. The results showed that the composite film could resist sulfuric acid corrosion at a concentration of 80% and inactivate Escherichia coli and Staphylococcus aureus at a concentration of 99%, and its maximum tensile strength was increased from the initial 2.753 to 4.145 N. The composite film was sensitive and specific for the fluorescence detection of sulfite.
