This book explores the use of graphene in heavy metal cleanup. The introductory chapter contains enough information for understanding graphene, including its synthesis, characterisation, and amazing mechanical, electrical, and thermal properties. The risks of compounds like lead, mercury, cadmium, and arsenic are also explained, along with the dangerous effects of heavy metals. The next chapters go into great detail about the ways by which graphene expertly adsorbs heavy metal ions. The ability of graphene to absorb heavy metals and the extraordinary adsorption characteristics that explain graphene&s efficiency in heavy metal removal are well explained. This book also shows how graphene may be dynamically combined with other materials to create potent nanocomposites with improved heavy metal cleanup capabilities. The environmental and safety implications of these ground-breaking solutions are also well given in detail. In addition to discussing the potential environmental issues associated with the discharge of graphene particles, the complexity of graphene dispersion, scalability, and cost-effectiveness are also covered. This book ends by looking towards the future prospects of how graphene will change its role in heavy metal cleaning and continue to advance in the same domain.   This book is an attempt to explore a cutting-edge area of materials science and environmental protection. It connects the extraordinary qualities of graphene, and heavy metal contamination in pursuit of a cleaner environment and is a good resource for scholars, academicians, and environmental practitioners by revealing a thorough examination of the crucial part that graphene plays in tackling heavy metal contamination.
