Degradasi Asam Humat Dengan Katalis TiO2/N Menggunakan Cahaya Matahari
— 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 TiO 2 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.
