Tea leaves extract as a natural reagent for quantification of copper using Sequential Injection Analysis (SIA)

Green chemistry system that utilizing natural extract as natural reagent for determination of metal ions has been investigated. The tea leaf extract has been utilized for copper quantification. The tea leaf extract was prepared in hot water (60 °C). Optimum condition obtained by 400 μL of tea leaves extract, 18 seconds of reaction time, 65 μL/s of flow rate and 0.078482 ppm of detection limit of Cu(II) ion. The tea leaf extract can be applied as a natural reagent for quantification of Cu(II) ion using Sequential Injection Analysis (SIA).
