Abstract

Humic acid is naturally generated from aerobic decomposition of organic matter by organisms. Treatment of humic acid by photocatalyst have some advantages, such as no saturation point, inexpensive, non-toxic and environmentally friendly. Photocatalyst is a photochemical process which involved catalyst and light illumination to generate radicals. This study was aimed determine the ability of photocatalysts to degrade humic acid using various ratios (1:1, 1:2 and 2:1) and concentrations of TiO2-Fe3O4 (2000, 6000, 10000 ppm) with UVC light as energy source. This research was carried out using the photocatalytic method, which determine optimum ratio and concentrations variation of TiO2-Fe3O4. The degradation data were obtained using a spectrophotometer UV-Vis with a wavelength of 254 nm. The optimum degradation percentage in the ratio variation test was 84,08%, at a ratio of 2:1. It caused by the ratio of 2:1 contains more TiO2 than Fe3O4. The optimum degradation percentage in the concentration variation test was 93,35%, at a 2000 ppm concentration. Due to, too much catalyst uses could be cause turbidity and block the light for absorption by the photocatalyst so that the photodegradation process becomes less effective.
