Abstract

Humic acid is a heterogeneous molecule of organic substance present in a peat water, which is carcinogenic is difficult to degrade. This study aims to degrade humic acid using the photocatalyst method is an environmentally friendly method. The photocatalyst used was TiO2 doped Nitrogen 8%. This study used reactor mobile hexagonal with variations in stirring speed, namely 500, 1000 rpm, and without stir with an irradiation time of 1 to 3 hours. Result of degradation analyzed using UV-Vis spectrophotometer. The degradation results obtained using strirring have a higher percentage of degradation than without strirring. The maximum degradation percentage obtained in this study was 76,27% with 500 rpm strirrings at 2 hours irradiation.
