Removal of sarafloxacin from aqueous solution through Ni/Al-layered double hydroxide@ZIF-8
AbstractIn recent years, excessive amounts of drugs such as antibiotics have been used to combat COVID-19 and newly discovered viruses. This has led to the production and release of significant amounts of drugs and their metabolites as toxic pollutants in aquatic systems. Therefore, pharmaceutical wastes must be removed efficiently before entering the environment and entering water sources. In this research, Ni/Al-LDH@ZIF-8 nanocomposite was synthesized from layered double hydroxides and metal-organic frameworks and used to remove the antibiotic sarafloxacin (SRF) in the aqueous medium. The work aimed to develop the perfor...

Physicochemical methods for disinfection of contaminated surfaces – a way to control infectious diseases
AbstractThis paper represents the reviews of recent advancements in different physicochemical methods for disinfecting contaminated surfaces, which are considered to be responsible for transmitting different bacterial, viral, and fungal infectious diseases. Surface disinfection can be achieved by applying chemicals, UV-based processes, ionization radiation (gamma-ray, X-ray and electron beam), application of self-disinfecting surfaces, no-touch room disinfection methods, and robotic disinfection methods for built-in settings. Application of different chemicals, such as alcohols, hydrogen peroxide, peracetic acid, quaternar...

Exposure to environmental pollutants: A mini-review on the application of wastewater-based epidemiology approach
AbstractWastewater-based epidemiology (WBE) is considered an innovative and promising tool for estimating community exposure to a wide range of chemical and biological compounds by analyzing wastewater. Despite scholars' interest in WBE studies, there are uncertainties and limitations associated with this approach. This current review focuses on the feasibility of the WBE approach in assessing environmental pollutants, including pesticides, heavy metals, phthalates, bisphenols, and personal care products (PCPs). Limitations and challenges of WBE studies are initially discussed, and then future perspectives, gaps, and recom...

Influence of Fe/Al oxyhydroxides and soil organic matter on the adsorption of Pb onto natural stream sediment
AbstractAdsorption of heavy metals on stream sediments has important implications for the fate and transport of contaminants in subsurface ecosystems. Lead (Pb) is a potentially hazardous heavy metal that is found in high amounts in anthropogenic environments, especially aquatic ecosystems. The key mechanisms for distributing this metal in the environment are adsorption and desorption in stream to sediment, and vice versa. Therefore, this work is mainly focused on the study of the influence of amorphous Fe/Al-oxyhydroxides and soil organic matter (SOM) on the adsorption of Pb onto natural stream sediment. Spiking adsorptio...

Preparation and characterization of CS/PAT/ MWCNT@MgAl-LDHs nanocomposite for Cd2+ removal and 4-nitrophenol reduction
AbstractThe present study evaluated the performance of multiwalled carbon nanotube (MWCNT)@MgAl-layered double hydroxide (LDH) nanoparticles loaded on poly-2 aminothiazole (PAT)/chitosan (CS) matrix (CPML) to remove Cd2+ ions from aqueous solution. The removal efficiency of modified CS/PAT with MWCNT@MgAl-LDHs was increased significantly compared to pure CS/PAT. The influence of heavy metal ion concentration, pH, temperature, adsorbent dosage, and contact time on the adsorption was examined. The optimum conditions for the adsorption of Cd2+ ions were 250C with the adsorbent dosage of 0.06  g and initial concentration for ...

Biodegradation behaviour of pharmaceutical compounds and selected metabolites in activated sludge. A forecasting decision system approach
AbstractSociety's support upon chemicals over the last few decades has led to their increased production, application and discharge into the environment. Wastewater treatment plants (WWTPs) contain a multitude of these chemicals such us; pharmaceutical compounds (PCs). Often, their biodegradability by activated sludge microorganisms is significant for their elimination during wastewater treatment. In this paper the focus is laid on two PCs carbamazepine (CBZ) and diclofenac (DCF) and their main transformation products (TPs). Laboratory degradation tests with these two pharmaceuticals using activated sludge as inoculum unde...

Simultaneous removal of phenoxy herbicides, 2-methyl-4-chlorophenoxyacetic acid and 2,4-dichlorophenoxyacetic acid from aqueous media by magnetized MgAl-LDH@Fe3O4 composite: application of partial least squares and Doehlert experimental design
In this study, a co-precipitation approach was used to create an MgAl-LDH@Fe3O4 magnetic adsorbent for the simultaneous removal of MCPA and 2,4-DCPA herbicides from aqueous solution. Using different techniques such as TGA, XRD, FESEM, EDS and zeta potential, we investigated the properties of the prepared adsorbent. The partial least squares method measures the concentration of each herbicide in their mixture. The optimization of MCPA and 2,4-DCPA simultaneous adsorption by LDH was achieved through Doehlert experimental design and the response surface method. The optimal conditions for absorption were determined to be an ad...

Optimization of divalent mercury removal from synthetic wastewater using desirability function in central composite design of response surface methodology
AbstractHeavy metals exist in the ecosystem both naturally and due to anthropogenic activities and as recalcitrant pollutants; they are non-biodegradable and cause acute and chronic diseases to human beings and many lifeforms. A statistical experimental approach was applied in this current study to optimize the detoxification of mercury [Hg(II)] from mono-component biosorption system by a novel hybrid granular activated carbon (biosorbent) prepared from maize plant residues. The analysis of variance by the application of central composite design shows that all the studied independent factors greatly influence Hg(II) remova...

Modification of cellulose with TiO2 nanoparticles: Potential solar driven photocatalyst and adsorbent
AbstractIn-situ modification of cellulose fibers with titania nanoparticles (TiO2 NPs) (TiO2 NPs-cellulose) was carried out via the sol –gel process using titania sol and fibers of cellulose. Cellulose fibers were extracted from wheat straw, an agricultural waste material, whereas titania sol was prepared from titanium(IV) acetoximate, [Ti{ONC(CH3)2}4]. The synthesized TiO2 NPs-cellulose composite was characterized by FT-IR, SEM –EDX, and XRD analyses. The obtained results exposed that TiO2 NPs were homogeneously dispersed over the surface of cellulose fibers. A study was conducted to compare the photocatalytic activit...
