Zinc acetate dihydrate {Zn(CH 3 COO) 2 •2H 2 O} and sodium hydroxide (NaOH) flakes were purchased from Fisher Scientific International, Inc. 30 ml of the tea extract was added to a beaker, after which 32.9265 grams of the zinc acetate dihydrate in its powdered form was added. The pH measured using a Vernier Go Direct pH Sensor was 5.12. The mixture was stirred for 30 minutes at 70°C. In another beaker, 20 ml of distilled water was added to 1.6 grams of sodium hydroxide to prepare a 2M NaOH solution. The solution was then tested for its pH, which was 14. The solution was then added dropwise to the zinc acetate dihydrate and the tea mixture until it reached a pH of 8. The solution was then stirred with a glass rod for 5 minutes. The solution was then placed in 10 small test tubes in order to be centrifuged for 5 minutes at 3500 rpm. The test tubes were then slowly decantated, and the precipitate, which settled, was washed with distilled water, before being centrifuged again for 5 minutes at 3500 rpm, followed by another decantation. The test tubes were dried for 5 hours in an oven at 200°C. The dried samples, in test tubes, were topped with 96% ethanol and stirred well. The contents were then filtered into a vial using a Whatman Grade 1 filter paper. The vials were then at room temperature in an airtight container for subsequent analysis and use .
