Persulfate Based Oxidation Processes In Environmental Remediation

Download or read book Persulfate-based Oxidation Processes in Environmental Remediation written by Mingshan Zhu and published by Royal Society of Chemistry. This book was released on 2022-03-25 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced oxidation processes (AOPs) use chemical treatment to remove contaminants from water by oxidation with hydroxyl radicals. These hydroxyl radicals can be produced using UV light, ozone or hydrogen peroxide, but recently reactions have been developed that use persulfates as the radical source. Persulfates are strong oxidants with flexible in situ activation characteristics, including activation with heat, alkali conditions, electricity, ultrasonic treatment, transition metals, carbon and even organics. Persulfate activation can generate sulfate radicals as well as other reactive species. These reactive species, especially the sulfate radical, can degrade most organic pollutants making them valuable in the fields of water purification, soil remediation, disinfection, sludge dewatering, and other important applications in environmental systems. Describing recent developments in persulfate-based AOPs, this book aims to provide a summary of environmental applications for persulfate-based AOPs and to guide the reader, in a comprehensive way, through various advanced oxidation processes in environmental applications. Topics include new activation methods, activation mechanisms, and advanced materials for use in activating persulfate-based AOPs for different environmental applications.

Download or read book Advanced Ozonation Processes for Water and Wastewater Treatment written by Hongbin Cao and published by Royal Society of Chemistry. This book was released on 2022-07-15 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozone has been actively and widely employed in water and wastewater treatment, but the utilization of ozone alone is insufficient for purifying and disinfecting water to the emission standard of real-world situations because of its selective oxidation behaviour. With the assistance of catalysts (especially heterogeneous catalysts) and coupling with other effective technologies such as the Fenton process, photocatalysis, electrocatalysis, ultrasound, microwave, and ceramic membranes, ozone can be effectively activated into more powerful reactive oxygen species (especially hydroxyl radicals). These combined technologies lead to an enhanced efficiency and complete mineralization capability that open up the method for more practical applications. Advanced Ozonation Processes for Water and Wastewater Treatment introduces the state-of-the-art catalysts used in catalytic ozonation and various combined processes with ozone. The reaction mechanisms, process kinetics, structure–property–activity relationships of catalysts, effects of operation parameters in these processes and the present state of practical applications and future trends are also discussed, making this a useful reference both for water treatment professionals and for those researching ozonation processes.

Download or read book Ionic Liquids for Environmental Issues written by João Coutinho and published by Royal Society of Chemistry. This book was released on 2023-11-17 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionic liquids (ILs) play a crucial role in modern chemistry and chemical engineering. They remain more desirable than conventional volatile solvents and catalysts in many physical and chemical processes, often exhibiting green and designer properties for various applications. Examining the unique contribution of ILs towards current environmental challenges, this book addresses the importance of their role in the detection of micropollutants and decontamination processes in air and water compartments. It also presents a detailed review of how ILs impact the environment once released, a topic seldom covered in other books, and highlights novel chemoinformatic tools used to predict their fate, showing how advanced oxidation processes help in remediation. This is an ideal book for researchers in both academia and industry, and postgraduate students in environmental chemistry, chemical engineering and analytical chemistry looking at the potential applications of ionic liquids in addressing several environmental problems.

Download or read book Environmental Nanopollutants written by Joanna Szpunar and published by Royal Society of Chemistry. This book was released on 2022-11-14 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanopollutants are nanoparticles that have escaped into the environment and can include engineered nanoparticles as well as nanoparticles that are products of degradation (e.g. nanoplastics) or other processes. As many of these particles are only recently developed or described there is still a lot to learn about where they come from, where they end up and what risks they pose to health and the environment. Offering a wide overview of the most recent research on these emerging contaminants, from the investigation of their sources and fate to the analytical developments for their detection and analysis, this book gives the reader a full picture of the global research on engineered and natural nanoparticles in the environment. Taking a forward-looking perspective with chapters on new nanopollutants, regulatory direction and occurrence in different environmental compartments, this book is a great resource for anyone working in environmental chemistry, nanoscience or environmental regulation.
