remazol blue19와 remazol black5가 혼합물 시료를 선택하여 촉매습식 산화공법으로 반응성 염료를 분해하였다. 용액중에서 반응성 염료의 분해효율과 분해생성물을 촉매습식 산화법으로 연구하기 위하여 촉매[Pt/TiO2 (wt. ratio : 5/100)] 첨가량, 반응온도 등을 조절하였다. 반응온도 250 ℃에서 혼합물 시료에 촉매를 1.0 g/L을 첨가하여 4 h 반응하였을 때 혼합물 시료의 TOC 잔존율과 UV 흡광 잔존율은 각각 4%이었다. 따라서 촉매를 사용한 이 공법은 용액중에서 반응성염료 혼합물, remazol blue19 + remazol black5 의 혼합시료의 분해에 효과적임을 알 수 있었다.


The degradation of reactive dyes, which consisted of a mixture solution of remazol blue19 and remazol black5, was studied using catalytic wet air oxidation process. To study decomposition efficiency and by-products formation of reactive dye in the catalytic wet air oxidation process, dosage of catalyst [Pt/TiO2 (wt.ratio : 5/100)] and reaction temperature were controlled. In the mixture sample, when the reaction time was 4 h at 250 ℃ with 1.0 g/L of catalyst, remaining percentages of both total organic carbon (TOC) and ultraviolet absorbance were 4 percent. This wet air oxidation process using catalyst was found to be an effective method for decomposition of the mixture sample solution consisting of remazol blue19 and remazol black5.
