Reactive dyestuffs (Red 195, Yellow 145, Blue 19) and Disperse dyestuffs (Red 60, Yellow 54. Blue 56) were photodegraded by UV irradiation with or without photocatalyst, TiO₂ powder. The photoreaction were conducted in a quartz annular reactor equipped with 39 w (x2) mercury lamp. The extent of decolorization and removal of organic compounds were 92%, 60% for Red 195 in reactive dyestuff with UV irradiation and were 98%, 99% for Red 195 in reactive dyestuff with UV irradiation and TiO₂ powder, respectively. The extent of decolorization and removal of organic compounds were 7%, 52% for Red 60 in disperse dyestuff with UV irradiation and were 96%, 94% for Red 60 in disperse dyestuff with UV irradiation and TiO₂ powder, respectively. These results were measured UV-Vis spectrophotometry and colors were calculated by platinum-cobalt standard method.
TiO<sub>2</sub> 고정화 지지체를 이용한 Chlorothalonil의 광촉매분해

$TiO_2$ 고정화 물질은 Titanium tetraisopropoxide-isopropanol 용액에 제오라이트와 glass filter를 담지한 후, 이것을 공기중에 건조시켜 $500^{\circ}C$에서 소결하여 얻었다. Chlorothalnoil의 분석은 ECD가 부착된 가스크로마토그래피로 분석하였다. Chlorothalnoil에 대한 분해효율은 $TiO_2$로 지지된 광촉매가 효과적이었고, 3시간 후 완전히 분해되었다. 반응 생성물들은 $TiO_2$로 지지된 제오라이트에서는 $Cl^-$가 5.0ppm, $TiO_2$로 지지된 glass filter에서는 $Cl^-$가 7.5ppm,그리고 $TiO_2$ 분말에서는 $Cl^-$가 2.0ppm 각각 생성되었다. 그러나, $CN^-$는 지지체의 종류에 관계없이 검출한계이하였다. $TiO_2$ was dispersed in zeolite and glass filter by soaking them in isopropanol solution of titanium tetraisopropoxide and drying in the air, followed by calcination at $500^{\circ}C$. The analysis of chlorothalnoil was carried out by gas chromatograph with an electron capture detector. Chlorothalnoil was degraded photocatalytically over the matrix-supported $TiO_2$ efficiently and could be completely photodegraded after 3hrs. Production were 5.0ppm of $Cl^-$ for $TiO_2$ supported zeolite, 7.5ppm of $Cl^-$ for $TiO_2$ supported glass filter and 2.0ppm of $Cl^-$ for $TiO_2$ powder. But, $CN^-$ was lower than the detection limit irrespective of matrices.
