This research aims to purify rice bran phenolic extract using dynamic adsorption-desorption method. This study used a Completely Randomized Design (CRD) Non Factorial with 1 level of treatment and each treatment was repeated 2 times. The treatment factors included 2 stages, including stage 1 which included variations in adsorption flow rates (1 BV/h, 2 BV/h, 3 BV/h, 4 BV/h, 5 BV/h, 6 BV/h, 7 BV…
