Effective degradation of tetracycline via persulfate activation using silica-supported zero-valent iron: process optimization, mechanism, degradation pathways and water matrices

Chemical activation and magnetization of carbonaceous materials fabricated from waste plastics and their evaluation for methylene blue adsorption

“…Hysteresis occurs when the adsorption and desorption curves do not overlap, primarily associated with the capillary condensation phenomenon that occurs in mesoporous structures during the desorption process. In this scenario, more hysteresis loops were observed for the activated and magnetic graphene, elucidating the enhanced formation of mesopores compared to pure graphene (Salama et al 2023a ; Salama et al 2024 ). Table 2 exhibits the improvement in surface area and porosity of the graphene after activation and magnetization.…”

“…Biological treatment processes cannot degrade emerging pollutants such as MB efficiently due to their bio-mutinous nature (Samy et al 2023 ). Further, chemical and physical processes such as electrocoagulation, ion exchange, coagulation, ozonation, photocatalysis, and membrane filtration are either expensive or produce secondary contaminants (Rashid et al 2021 ; Salama et al 2022a ; Salama et al 2022b ; Salama et al 2023a ). Recently, researchers have focused on removing emerging pollutants via the adsorption method due to its effortless and high decontamination performance compared to the aforementioned techniques (Diab et al 2021a ; Salama et al 2022b ).…”

Co-based MOF as an efficient catalyst by peroxymonosulfate activation for degradation of tetracycline: synthesis and performance

“…It had been reported that TC compounds had been detected in water, soil, sewage, and activated sludge because of their strong persistence in water and poor biodegradability. 3,4 In recent decades, advanced oxidation processes (AOPs) such as ozone oxidation, photocatalysis, Fenton oxidation, and persulfate oxidation have been widely used in the removal of TC in water. 5,6…”
