Abstract

Abstract: This research aims to determine the ability of andisol which is composited with TiO2 as a degrading agent of Rhodamine B dye. The composite was made by sonication and calcination. Each material was characterized by FTIR and XRD. Photodegradation was carried out under a UV lamp with variation of the degradation time for 1, 2, and 3 hours. While the pH variation was carried out at 3, 5, 7, and 9. The photodegradation results were tested using UV Vis spectrophotometer at wavelength of 552 nm. Based on these results, the optimum conditions for photodegradation at pH 5 with irradiation time of 2 hours was 39.55%.
