Cellulose Filter

In this study, a polydopamine (PDA) and polyethyleneimine (PEI)-assisted approach was developed to generate well-distributed PDA/PEI/silver (PDA/PEI/Ag) nanocomplexes on the surfaces of commercial cellulose filter papers to achieve substantial bacterial reduction under gravity-driven filtration. PDA can bind to cellulose paper and act as a reducer to produce silver nanoparticles (AgNPs), while PEI can react with oxidative dopamine and act as a dispersant to avoid the aggregation of AgNPs. The successful immobilization of PDA/PEI/Ag nanocomplexes was confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) were used as pathogen models to test the efficacy of the PDA/PEI/Ag nanocomplex-incorporated filter papers. The PDA/PEI/Ag nanocomplex-incorporated filter papers provided a substantial bacterial removal of up to 99% by simple gravity filtration. This work may be useful to develop a feasible industrial production process for the integration of biocidal AgNPs into cellulose filter paper and is recommended as a local-condition water-treatment technology to treat microbial-contaminated drinking water.

Abstract In general, spent adsorbent is regenerated using high-concentration chemicals. Although chemical regeneration is efficient, it often leads to adsorbent damage and secondary waste. To overcome these problems, electro-assisted and photo-assisted regeneration were proposed in this study for the remediation of hexavalent chromium (Cr(VI)). Filter paper was decorated with polyethylene glycol (PEG) and polypyrrole (PPy) to fabricate a FP/PEG/PPy nanocomposite, which could be used as an adsorbent for Cr(VI) with a high adsorption capacity. Moreover, it could be regenerated by electro-assisted or photo-assisted regeneration to reduce eluent use. As a result, secondary waste could be greatly reduced.

Four bioassays for use in detecting and measuring insecticide resistance in newly-emerged, unfed adult cat fleas, Ctenocephalides felis (Bouché), were evaluated: horizontal glass, horizontal Nylon 6,6 fabric disk, horizontal cellulose filter paper disk, and vertical cellulose filter paper strip (WHO bioassay). Each bioassay was evaluated using five insecticides: carbaryl, chlorpyrifos, malathion, permethrin, and pyrethrum. LC50s, LC90s, probit line slopes, and slope standard errors were compared. The LC50s on glass were lower than those obtained with the other substrates. This difference was at least an order of magnitude with carbaryl, malathion, permethrin, and pyrethrum. The paper disk and paper strip bioassays produced the highest LC50s and LC90s for fleas treated with carbaryl, malathion, and pyrethrum. With chlorpyrifos and permethrin, the paper strip resulted in the highest LC50s. The nylon disk tended to produce LC50s intermediate between glass and filter paper. On glass, chlorpyrifos generated higher LC50s (2.00 mg[AI]/m2) than permethrin (0.927 mg[AI]/m2) or pyrethrum (0.913 mg[AI]/m2), yet on the paper strip was lower (65 mg[AI]/m2) than permethrin (214 mg[AI]/m2) or pyrethrum (466 mg[AI]/m2). Overall, probit line slopes were highest for glass and WHO. Standard errors of the slope were not significantly different among bioassays. Although nylon disk assay possibly simulates chemical-substrate interactions on carpet, which is a common substrate where cat fleas occur, no single substrate gave acceptably precise probit lines for all chemicals tested, and chemical efficacy depended on the substrate used. Chemical-substrate interactions confound detection of insecticide resistance and chemical efficacy.
