“…To the best of our knowledge, the results achieved by utilizing a 100 mg L −1 dose of Basolite ® F300 in this study are highly competitive when compared to other heterogeneous catalysts that have been previously researched. This work was compared to previous studies that tested the insertion of heterogeneous catalysts directly in solution to catalyze the degradation of TC at various doses in Table 1 [44][45][46][47][48][49]. When considering the catalyst dose, degradation time, and the facile synthesis of the already commercially available material, it becomes evident that this study shows that the use of Basolite ® F300 is most advantageous.…”

This study explores the use of the iron-containing metal–organic framework (MOF), Basolite®F300, as a heterogeneous catalyst for electrochemically-driven Fenton processes. Electrochemical advanced oxidation processes (EAOPs) have shown promise on the abatement of recalcitrant organic pollutants such as pharmaceuticals. Tetracyclines (TC) are a frequently used class of antibiotics that are now polluting surface water and groundwater sources worldwide. Acknowledging the fast capability of EAOPs to treat persistent pharmaceutical pollutants, we propose an electrochemical Fenton treatment process that is catalyzed by the use of a commercially available MOF material to degrade TC. The efficiency of H2O2 generation in the IrO2/carbon felt setup is highlighted. However, electrochemical oxidation with H2O2 production (ECO-H2O2) alone is not enough to achieve complete TC removal, attributed to the formation of weak oxidant species. Incorporating Basolite®F300 in the heterogeneous electro-Fenton (HEF) process results in complete TC removal within 40 min, showcasing its efficacy. Additionally, this study explores the effect of varying MOF concentrations, indicating optimal removal rates at 100 mg L−1 due to a balance of kinetics and limitation of active sites of the catalysts. Furthermore, the impact of the applied current on TC removal is investigated, revealing a proportional relationship between current and removal rates. The analysis of energy efficiency emphasizes 50 mA as the optimal current, however, balancing removal efficiency with electrical energy consumption. This work highlights the potential of Basolite®F300 as an effective catalyst in the HEF process for pollutant abatement, providing valuable insights into optimizing electrified water treatment applications with MOF nanomaterials to treat organic pollutants.

“…The results showed that this catalyst has promising applications in the removal of organic matter. [28] Based on this, in this experiment we explore the removal effect of Fenton reagent on common drugs in wastewater, in order to meet normalized needs of wastewater treatment plants for safe, environmentally friendly and economical removal of illicit drugs from wastewater. In addition, the main method of detecting drugs in wastewater is through solid phase extraction and liquid-liquid extraction for sample purification and enrichment, combined with liquid chromatography-mass spectrometry (LC-MS/MS) for analysis.…”

Drugs and their metabolites have become new types of pollutants, the presence of which constitutes a serious environmental problem. This article applies the established LC–MS/MS method to investigate the removal efficiency of different ratios of Fenton reagents for common drugs in wastewater. The results showed that the linearity of the 10 common drugs was good in the dynamic range of 1–100 ng/L, and the R2>0.99. The LODs and LOQs ranged from 0.01–0.443 ng/L and 0.04–1.44 ng/L, respectively. The average relative recoveries ranged from 72.99–117 %. In addition, considering the economic and application effects of chemical reagents, the optimal test dose of H2O2 in Fenton reagent was determined to be 12.5 mL. This experiment provides a simple, rapid and low‐cost LC–MS/MS method for the detection of drugs in wastewater. It also provides data reference for effective management of drug production sites and domestic wastewater pollution.

Silica‐based nanomaterials have attracted huge attention for maximizing their safety and efficacy due to their nontoxicity, chemical and thermal stability, size tunability, and versatile functionality. Nanosilica with ZnO or carbon in a composite has excellent usage as an electrochemical sensor. Recent technological progression in nanotechnology and nanoscience has seen a number of applications of zinc oxide (ZnO) nanomaterials ranging from electronics, and sensing to environmental, and biomedical applications because of its various applications, multifunction, high specific surface area, stability, biocompatibility, nontoxicity, electrochemical activities, and so on. Carbon also has various advantageous properties like renewability, low ohmic resistance, and very stable response due to which carbon paste electrodes have attracted attention in the fabrication of electrochemical sensors. Electrochemical sensors are inexpensive, portable, and have excellent ability in detecting water contaminants, pesticides, disinfectants, pathogens, and different molecules. Artificial dyes are usually mixed with vegetable sauces, drinks, and other food items, which can cause cancer in human body. Voltametric methods with electrochemical sensors can be used to detect them in food samples. In this review, the present applications of ZnO and carbon nanomaterial‐based chemical sensors are meticulously studied to detect water contaminants and food dyes where nanosilica plays an important role as a sensor modifier.
