I have been working on my master thesis for optimisation a surfactant named Tergitol(NP10) with UVC/H2O2 .Could you please suggest me some methods to measure residual peroxide and hydroxyl radicals?Thanks in advance...
Dear Hatice:
Detection of hydroxyl radicals look:

Regards.
Hydroxyl radical are very short lived so you cannot measure a residual concentration of them. The method Yuri links to is for measuring how many radicals there have been produced during a treatment.
Hydrogen peroxide can be measured with either titration or colorimetrically. For laboratory experiments I prefer the color reaction with titanium oxalate as it is quite cheap, simple and effective in the low mg/L range. The method is described in the supporting information to the article linked to this answer.

Dear Dr. Anderson,
Regarding measurement of hydroxyl radicals, can we measure it indirectly?
In water treatment hydroxy radicals are very short lived so you will not have a residual.
It is possible to measure products of their reaction and if this is done with a calibrated method you can use it to know how many hydroxy radicals there have been during the treatment. The method Yuri refer to does this.
