Why absorption of methylene blue increases and decreases during photodegradation while it takes concentration decreases over time.
Dear Khaled,
In principle, you should not see oscillations in the uv-vis spectrum. Sometimes there is interference from the additives involved in the reaction. If you use H2O2 as your oxygen source, you have to see if the peroxide interferes with your photodegradation process, but nothing else should cause these oscillations.
Best,
Fran

Dear Francisco Manuel Marquez ,
Thank you for your response.
No I do not use H2O2.
