Sorption-based atmospheric water harvesting (SBAWH) is a highly promising approach for extracting water from the atmosphere thanks to its sustainability, exceptional energy efficiency, and affordability. In this work, ZnFeO and ZnCoFeO were evaluated for moisture adsorption. The desired materials were synthesized by a surfactant-assisted sol-gel method.

Article Synopsis
  • Industrial wastewater significantly pollutes water resources, prompting the need for effective treatment methods, like coagulation-flocculation, to remove contaminants.
  • Natural coagulants and flocculants (NC/Fs), though cost-effective and biodegradable, are often overlooked for large-scale industrial applications, with most existing research focusing on plant-based sources.
  • This review broadens the exploration of NC/Fs by examining alternative natural materials, detailing preparation techniques, discussing recent studies, and highlighting the potential of magnetic-natural coagulants/flocculants (M-NC/Fs) in large-scale effluent treatment systems.

Recently, efficient decontamination of water and wastewater have attracted global attention due to the deficiency in the world's water sources. Herein, activated carbon (AC) derived from willow catkins (WCs) was successfully synthesized using chemical modification techniques and then loaded with different weight percentages of nickel ferrite nanocomposites (10, 25, 45, and 65 wt.%) via a one-step hydrothermal method.

In many nations, particularly those experiencing water scarcity, novel approaches are being applied to clean wastewater. Heterogeneous photocatalysis is the most widely used of these approaches because it entails the decomposition of organic molecules into water and carbon dioxide, which is a more ecologically benign process. In our study, we studied the photocatalytic degradation process on the effluent flumequine.

Nowadays, in parallel to the appearance of the COVID-19 virus, the risk of viruses in water increases leading to the necessity of developing novel disinfection methods. This review focuses on the route of virus contamination in water and introduces non-thermal plasma technology as a promising method for the inactivation of viruses. Effects of essential parameters affecting the non-thermal discharge for viral inactivation have been exposed.

Excessive levels of dyes and heavy metals in water sources have long been a source of concern, posing significant environmental and public health threats. However, adsorption is a feasible technique for removing dye contaminants and heavy metals from water due to its high efficiency, cost-effectiveness, and easy operation. Numerous researchers in batch studies extensively evaluated various adsorbents such as natural materials, and agriculture-derived and industrial wastes; however, large-scale application is still missing.
