Lab-Scale Liquid-Liquid Extraction Procedure for Caffeine from Tea

This document outlines a lab-scale liquid-liquid extraction (LLE) procedure for determining caffeine content in tea. The method involves shaking cooled tea with methylene chloride (CH2Cl2), an organic solvent, which effectively extracts caffeine, a solid compound present in the beverage. After the extraction process, the caffeine concentration can be analyzed to assess the tea's caffeine content. This procedure serves as a practical example for students and researchers interested in analytical chemistry techniques.
