Catalysts, Год журнала: 2024, Номер 14(3), С. 189 - 189

Опубликована: Март 10, 2024

A large variety of pharmaceutical compounds have recently been detected in wastewater and natural water systems. This review highlighted the significance removing compounds, which are considered indispensable emerging contaminants, from Various advanced oxidation processes (AOPs), including UV-H2O2, Fenton photo-Fenton, ozone-based processes, photocatalysis, physical such as sonolysis, microwave, electron beam irradiation, regarded most viable methods to eliminate different categories discussed. All these AOPs exhibit great promising techniques, catalytic degradation process advantages, disadvantages each technique were deliberated. Heterogeneous photocatalysis employing metal oxides, particularly anatase TiO2 nanoparticles catalysts activated by UV light was reviewed terms electron–hole separation, migration charge carriers catalyst surfaces, redox potential carriers. brief overview also emphasized that TiO2-based nanomaterials photocatalysts, a combination other enhanced photocatalytic efficiency. Finally, challenges applying environmental remediation treatments degrade mass spectroscopic analysis biological activity test by-products contaminants resulting summarized.

Photocatalytic removal of imidacloprid pesticide from wastewater using CdS QDs passivated by CQDs containing thiol groups

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Янв. 4, 2024

Over the past decade, CdS QDs have become versatile semiconductors. Surface modification of has an interesting case study, as it can eliminate surface defects and improve their photochemical properties. In this we report a new strategy using carbon quantum dots containing large number thiol groups (CQDs-SH) passivating agent for stabilization (QDs). Various characterization techniques clearly revealed that been successfully passivated by CQDs-SH. The photocatalytic performance CQDs-SH/CdS was investigated degradation insecticide imidacloprid from aqueous solution. Parameters affecting photodegradation process, including light source, photocatalyst amount, initial concentration pollutant, radiation time, pH, oxidizing agent, temperature, were investigated. Furthermore, HPLC technique applied to quantitatively analyze its products. results analysis under simulated visible at pH 9, scarcely existed after 90 min irradiation (90.13% degradation). LC-MS method also used detect products investigate mechanism pesticide. showed composite promising in wastewater.

Advanced oxidation processes for the decontamination of heavy metal complexes in aquatic systems: A review

Case Studies in Chemical and Environmental Engineering, Год журнала: 2023, Номер 9, С. 100567 - 100567

Опубликована: Ноя. 30, 2023

A significant challenge in industrial wastewater treatment is the presence of heavy metal complexes (HMCs) formed when metals interact with organic complexing agents. These HMCs exhibit greater stability compared to free ions, making them resistant degradation and removal via conventional methods. The HMC has spurred extensive research into effective Conventional systems, including adsorption, precipitation/electrodeposition, ion exchange, membrane filtration, often fall short removing HMCs. In recent years, advanced oxidation processes (AOPs) have emerged as a promising approach for effectively degrading AOPs, class chemical utilizing reactive oxygen species (ROS), degrade pollutants decompose readily removable ions. This review provides quantitative assessment viability AOPs detoxification through decomposition. It explores various used from wastewater, highlighting their advantages limitations. influence experimental factors mechanisms involved by are also discussed. Finally, potential applications challenges remediation critical intended be valuable resource engineers, chemists, environmental scientists who use treat containing HMC. decomposing but expensive energy intensive. More needed develop new that efficient cost-effective.
