A SURVEY OF ANALYTICAL METHODS EMPLOYED FOR MONITORING OF ADVANCED OXIDATION/REDUCTION PROCESSES FOR DECOMPOSITION OF SELECTED PERFLUORINATED ENVIRONMENTAL POLLUTANTS
Trojanowicz, M., K. Bobrowski, B. Szostek, A. Bojanowska-Czajka, T. Szreder, I. Bartoszewicz, and K. Kulisa. Talanta 177:122-141(2018)

Advanced oxidation/reduction processes (AO/RPs) include photolytic and photocatalytic processes, Fenton reactions, sonolysis, ozonation, application of ionizing radiation, and several wet oxidation processes. The monitoring of AO/RPs to evaluate the yield and mechanisms of decomposition of perfluorinated compounds such as PFOA or PFOS can be more difficult than their determination in samples with complex matrices, likely due to the formation of hundreds or even thousands of intermediate and final products. This review discusses the use of LC/MS/MS, GC/MS, molecular spectrophotometry (especially electron paramagnetic resonance), UV/Vis spectrophotometry with pulse radiolysis methods, ion chromatography, and potentiometry with ion-selective electrode for the measurement of perfluorinated compounds.
