2. Photodiscomposition of
surface active agent
• Photocatalysic degradation and oxidation are technologies
developed in the recent 30 years.
• Advantages: low cost, mild reaction conditions, no
secondary pollution.
• Reaction speed:
anionic>cationic
aromatic ring part>methyl part
• The degradation speed constant K is only related to the
light source, catalysic activity and the reaction medium
rather than the surface active structure. 。
