UV-vis investigation of (CTC/Orthodox/Green) tea in presence of Brij 35/Water systemDOI: 10.3126/bibechana.v11i0.10378, PP. 40-45 Keywords: CTC tea,Orthodox tea,Green tea,Brij 35,Water,UV-vis Abstract: The precise measurements of (CTC/Orthodox/Green) Tea absorbance in presence of Brij 35/Water system at room temperature by UV-vis technique are reported. The concentrations of Brij 35 [Polyoxyethylene lauryl ether] were varied from 0.01 to 0.02 mol/lt. Tea concentration in quvette during UV-vis spectrum registration was the same. Obtained results showed a noticeable decreasing of Tea absorbance as a function of Brij 35 concentration. There is evidence of Tea absorbance in the following order: Orthodox > CTC >Green.
