| Abstract: |
| Advanced oxidation processes（AOPs）are widely applied to the treatment of organic pollutes， especially the treatment to the pollute that is hard to be removed by other methods. It is necessary to conduct qualitative and quantitative analyses on free radicals as the formation of strong oxidizing free radicals is the key factor in AOPs. An overview on the determination methods for free radicals generated from AOPs is provided in this paper， which include electron spin/paramagnetic resonance，high performance liquid chromatography， spectrophotometry， fluorescent spectrometry and electrochemical methods. The advantages and disadvantages of these methods are elaborated by comparing their veracity， accuracy and selectivity in qualitative and quantitative analysis processes. Finally， the perspectives for the development and application of these methods are further proposed in the paper. |
