| Abstract: | An effective and easily recovered porous divinylbenzene (DVB) cross-linked antimicrobial polymeric resin containing N-halamine functional groups, poly (styrene-co-N-(t-Bu)-N-chloro-acryl amide) (PSA-N-Cl) resin, has been synthesized by a suspension copolymerization of styrene and acrylic acid and DVB, an amination with tert-butylamine and triethylenediamine (TEDA), and then a facile chlorination in diluted NaOCl solution. The as-prepared porous DVB cross-linked PSA-N-Cl resin was characterized by Brunauer–Emmett–Teller (BET) analysis, field emission scanning electron microscopy (FE-SEM), Fourier Transform infrared spectroscopy (FTIR) and X-ray photoelectron spectra (XPS). BET analysis indicated that PSA-N-Cl resin has a very large surface area (124.9 m2/g) which is favorable for the quick water disinfection. Antibacterial tests showed that the as-prepared PSA-N-Cl resin possesses powerful antibacterial efficacies against both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The as-prepared PSA-N-Cl resin was capable of about 7.95-log and 7.81-log reductions of E. coli and S. aureus within 1 and 3 min of contact times, respectively. Also, the regenerability and preliminary storage stability of the as-prepared PSA-N-Cl resin were investigated. |
