Caffeine Analysis in Tea Using UV-Vis by bishnoiarman91 is a document available to read on EtoBox.
This investigatory project aims to determine the percentage of caffeine in a tea sample using UV-Visible spectrophotometry and a calibration curve. The procedure involves preparing standard caffeine solutions, measuring their absorbance, and using this data to calculate the caffeine concentration in the tea extract. The final results indicated a caffeine percentage of 0.5251% (w/w) in the tea sample, with precautions outlined to ensure accuracy.
