Abstract:
The high number of dissolved organic matter such as humic acid and its derivatives as well as the color of peat water causes the water not suitable for use as a source of clean water. Processing needs to be done beforehand to make it as a source of clean water. TiO2-zeolite has been used for photodegradation of organic matter and color on peat water. TiO2-zeolite was synthesized from natural zeolite and TiO2 which were mixed in ethanol 99% and characterized by XRD and XRF. The effect of TiO2-zeolite for photodegradation of organic matter and color of the peat water was done by varying the time of UV light irradiation and TiO2-zeolite mass. The results showed that the TiO2-zeolite can reduce the content of organic matter and color of peat water. The decrease in organic matter reached 80.41% and a decrease in color intensity reached 60.39% on UV light irradiation for 5 hours using 375 mg of TiO2-zeolite
