Abstract

Cellulose acetate (CA), and CA blended with Nicotiana tabacum ash (ACA) membranes have synthesized and fabricated with zero-valent Fe NPs (ZVI) and named as CA@Fe⁰ and ACA@Fe⁰. The as-synthesized membranes were inspected for the removal and detoxification of toxic organic pollutants. Comparative studies of CA@Fe⁰ and ACA@Fe⁰ NPs were investigated for five model pollutants, such as 4-nitrophenol (4NP), methyl orange (MO), Congo red (CR), methylene blue (MB), and bromocresol green (BCG). The kinetic model indicated that the apparent rate constant K_app value of ACA@Fe⁰ was highest for all model pollutants compared to CA@Fe⁰ NPs. The K_app value is derived from pseudo-first-order kinetics. The K_app value of MO discoloration was 8.17 × 10⁻¹ min⁻¹ with ACA@Fe⁰ which is highest than CA@Fe⁰ (3.08 × 10⁻¹ min⁻¹). The turnover frequency (TOF) was highest for ACA@Fe⁰ for all the pollutants compared to CA@Fe⁰ and the highest TOF value was found for CR dye with ACA@Fe⁰ which is 0.523 h⁻¹. Both the membranes also showed promising antibacterial activity against Salmonella typhi. Furthermore, CA, ACA membrane and CA@Fe⁰ and ACA@Fe⁰ NPs were characterized through FESEM, EDS, XRD, FTIR and TGA analysis.
