Photocatalytic destruction of anionic SAS with oxygen and hydrogen peroxide in the TiO2 suspension

The articles gives a comparison of the rates and the degree of destruction of anionic SAS-alkyl benzene sodium sulfonate (ABS) in heterogeneous (O 2 /TiO 2 /UV, H 2 O 2 /TiO 2 /UV) and homogeneous (O 2 /UV, H 2 O 2 /UV) oxidizing systems on several TiO 2 samples at UV irradiation by a SVD-120 high-p...

Description
Summary:The articles gives a comparison of the rates and the degree of destruction of anionic SAS-alkyl benzene sodium sulfonate (ABS) in heterogeneous (O 2 /TiO 2 /UV, H 2 O 2 /TiO 2 /UV) and homogeneous (O 2 /UV, H 2 O 2 /UV) oxidizing systems on several TiO 2 samples at UV irradiation by a SVD-120 high-pressure mercury-quartz lamp. The paper has demonstrated a possibility of achieving a high degree of photocatalytic destruction of ABS by hydrogen peroxide (100, 90, and 80% respectively by the ABS concentration of ABS, COD, and TOC over two hours).
