Abstract—Techniques for sample separation from chemical reaction is an important step in a synthesis process. Two techniques, filtration and centrifugation, were used for separating the synthesized TiO2 precipitates in this study. Photocatalytic activities of the synthesized TiO2 and P25 were evaluated through the degradation of methylene blue (MB). The results show that the MB degradation of the TiO2 powder obtained from the centrifugation technique is higher than that from the filtration technique due to its smaller particle size and larger content of anatase.
