Green and Sustainable Analytical Chemistry focuses on developing environmentally friendly and resource-efficient analytical methods. The goal is to minimize the use of hazardous chemicals, reduce waste generation, and lower energy consumption while maintaining accuracy and reliability. This approach emphasizes solvent-free or solvent-reduced techniques, miniaturization, and the use of biodegradable materials and renewable resources. Methods such as solid-phase microextraction (SPME), microwave-assisted extraction, and miniaturized sensors are commonly used. Sustainable practices are integrated throughout the analytical process from sample preparation to detection promoting safety and environmental responsibility. Green analytical chemistry plays a vital role in environmental monitoring, pharmaceutical analysis, and industrial quality control. As global awareness of ecological impact grows, adopting sustainable methods is essential for responsible scientific progress and regulatory compliance.
