    摘要: 本研究利用TiO2進行光催化反應去除水中有機物。本研究主要目的有為:以溶膠-凝膠法製備二氧化鈦及氫氧磷灰石,利用二氧化鈦經紫外光照射後產生氧化作用,以及磷灰石對有機物可吸附之特性將二者結合,以酚與甘胺酸為反應物,使用不同比例二氧化鈦/磷灰石所合成之觸媒,由上述反應物去除率篩選最適之TiO2/Apatiet光觸媒及最適之觸媒添加量。
    This study aimed at removing organics in aqueous solution via photo catalysis. A more efficient photo catalyst, i.e. TiO2/Apatite, was synthesized by the sol-gel method. The improved efficacy of TiO2/Apatite may be attributed to the combination of photo catalytic capability of TiO2 and absorption capability of Apatite. The organics tested were phenol and glycine (an amino acid) and their removing efficiency were based to screen for the optimal catalyst loading and composition of TiO2/Apatite.
    The results show that Apatite has the most BET surface area as it was prepared at Apatite/P.P. = 1:1. Moreover, for removing phenol, the optimal ratio of TiO2/Apatite is 5:1 while it is 9:1 for the removal of glycine. The most efficient catalyst loading is 0.75 g/L for both organics tested.
    Under the above mentioned optimal reaction conditions, the following efficiency was obtained. For 100ppm phenol, 45 % phenol conversion and 24 % COD removal was achieved after 6 hrs reaction;for 50 ppm, 55 % phenol conversion and 35 % COD removal was achieved after 4 hrs reaction;for 100 ppm glycine, 50 % COD removal was achieved after 4 hrs reaction.
