“…Despite the importance of water to human and environmental health, this valuable natural resource has become one of the primary sources of numerous contaminants such as heavy metals, endocrine disruptors, dyes, organics, and antibiotics (Lou et al 2019;Tian et al 2019;Zhang et al 2019). Of even pressing concern is the presence of microbial pathogens that can be transmitted to humans and other animals, with severe public health consequences, especially during outbreaks.…”

Herein, we successfully synthesized nano-porous Co 2 O 3 /Cu 2 O 3 : Al 2 O 3 : SiO 2 ((0, 5, 7, 9) Co-CAS) using the acidic sol-gel approach and calcined at 800°C for 4 h. The crystallization behavior and spectroscopic properties were investigated using X-ray diffraction, field emission-scanning electron microscopy, and Fourier-transform infrared absorption spectra analysis. The antibiotic properties of the nano-porous CAS, 5Co-CAS, and 9Co-CAS magnetic nanocomposites was studied against some potentially pathogenic bacteria in water and wastewater samples. The bacteria tested included Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, Listeria monocytogenes, Staphylococcus aureus, Enterococcus faecalis, and Bacillus subtilis. Incorporating Co 2 O 3 resulted in the identification of three peaks at 2θ = 10.2°, 13.4°, and 15°. The introduction of cobalt nanoparticles created a ferromagnetic behavior in the CAS nanoceramic, with the magnetic moment and saturation values increasing with increased Co 2 O 3 doping. 9Co-CAS was most potent against all the tested pathogens with minimum inhibitory concentrations of 25 mg/L within 40 min for E. coli and P. aeruginosa and 50 mg/L within 10 min for S. enterica; the lowest antibacterial activity was observed with the unmodified CAS. The findings revealed that the manufactured nanocomposite materials were potent disinfectants with a promising application for water and wastewater treatment.

“…3 Compared with biological processes, advanced oxidation technology has the obvious advantages of fast reaction rate and high efficiency in removing refractory organic pollutants from complex wastewater. 5,6 Recently, the rapid removal of Qu by radical oxidation of sulfate has attracted much attention in persulfate (PS)-based systems in early neutral pH wastewater due to its high redox potential and excellent selectivity. 7,8 Ferrous ion is reported as one of the strongest activators in the PS-based system.…”

“…1 At present, the common methods of treating organic pollutant in wastewater are in-situ burning, 2 microbial degradation, 3 chemical dispersant, 4 photoelectrocatalysis, 5,6 and adsorption. 7,8 Among these methods, the most effective methods to remove organic pollutants in a short time are in situ burning, but some harmful gases release by burning could cause environmental pollution. Microbial degradation, as an important method for the removal of organic pollutants, is restricted by the low bioavailability.…”

Three‐dimensional, inexpensive and environmentally friendly adsorbent materials were urgently in demand for the absorption of organic compounds. In this study, the 3D ultralight sponge was assembled from fragmented electrospun nanofibers of polyacrylonitrile (PAN) and natural loofah. The PAN nanofibers and loofah short fibers were dispersed in an aqueous solution using polyvinyl alcohol (PVA) as the adhesive, and then formed the 3D ultralight sponge by freeze‐drying technology. By adjusting the content of loofah, a kind of spider web structure which was beneficial to enhance oil adsorption was developed arising from polymers dissolution and reconstruction. At the same time, the loofah was integrated with the PAN by ‐OH···N≡C‐ hydrogen bonds to stabilize the structure. Finally, due to the high porosity (99.3%), low density (7.63 kg/m3) and unique spider web structure, our prepared PAN/loofah sponges could absorb organic compounds up to 177 times of their own weight. Hence, the developed PAN/loofah sponge as an environmentally friendly adsorbent would be promising in wastewater treatment.
