Abstract
Peat water sources could be found in many lowland and marshy areas in Indonesia such as in Sumatra, Kalimantan, and Papua. The water could be a problem for residents living around it because it formed from decayed plants, animals, and microbes. The main component of it is humic acid which is a complex of organic compound and natural polymer. This research aims to conduct the activity of PVDF-TiO2/ZnO/CoO nanofiber photocatalyst for degradation of humic acid solution. Photocatalytic activities were studied inside a photoreactor with artificial UV radiation with 254 nm wavelength. The percentage of degradation was determined by measuring humic acid solution before and after degradation using UV-Vis spectrophotometer with maximum lambda is 219 nm. The study of kinetic for a photocatalytic reaction was calculated with rate constant 4,29 x 10-5 min-1 ppm-1 and the kinetic of photodegradation on this research was pseudo second-order kinetic model.
