"Sustainable waste management is one of the most critical challenges of our century. As industrialization and urbanization accelerate, the management of wastewater and solid waste requires scientific, precise, and actionable solutions. Analytical chemistry serves as the backbone of this effort. It provides the tools and methodologies needed to detect pollutants, monitor treatment efficiency, and ensure environmental compliance.This work, titled "Sustainable Waste Management: Analytical Chemistry Applications of Wastewater and Solid Wastes," bridges the gap between theoretical chemistry and practical environmental engineering. It offers a comprehensive overview of how modern analytical techniques are applied to characterize, treat, and recycle waste streams. From advanced spectroscopic methods to chromatographic separation, each chapter explores how chemical analysis drives sustainable decisions and technological innovations.This book is prepared for researchers, environmental engineers, chemists, and policymakers. It aims to serve as a valuable reference for understanding the chemical complexities of waste.
