Discover a groundbreaking new wastewater decontamination technology
The removal of wastewater contaminants is a key aspect of the water cycle, allowing water to be fed safely back into circulation within a given ecosystem. Metal-Organic Frameworks (MOFs) are a new class of porous materials which can reversibly bind and sequester both metal ions and potentially harmful organic substances, giving them a potentially crucial role in the targeted removal of wastewater contaminants. They may also enable significant cost and energy savings over now-conventional ion exchangers in water treatment plants.
Metal Organic Frameworks for Wastewater Contaminant Removal provides an accessible, practical guide to the development, evaluation, and potential applications of MOFs in maintaining the water cycle. It begins with an overview of the major metallic and non-metallic contaminants found in wastewater and their interactions with major MOF-based materials, before moving to the challenges and opportunities provided by MOFs in the pursuit of a sustainable, energy-efficient water cycle. The result is a groundbreaking resource in the ever-expanding global fight to keep water clean and safe.
Metal Organic Frameworks for Wastewater Contaminant Removal readers will also find: - MOF technology and its water treatment applications discussed in depth for the first time in a major publication - Comparison with existing decontamination technologies and environmental risk assessment - Applications for environmental as well as industrial toxicants based on recent research and on case studies
Metal Organic Frameworks for Wastewater Contaminant Removal is indispensable for water chemists, chemical engineers, environmental chemists, and for any researchers or industry professionals working with water decontamination technologies.
