Abstract

A new photocatalyst supports based on biomaterials surface is proposed to apply for titania semiconductor. Biomaterials such as Talang Bamboo, Coconut Shell, and Surian Wood was prepared as TiO2 / Biomaterials reactor in peat water purification. Peat water was irradiated using sunlight in TiO2 / Biomaterials photochemical reactor in order to determine the capability of photochemical reactor to purifythe peat water and also to measure the stability of the reactor. As the result of irradiation in 10 hours the organic component was decreased about 66% respectively for all 3 kinds of biomaterials. Found that the pH was increased until 6.50 and Fe ions content was also decreased.
