Detection and characterisation of free radicals in Guneshli oils using electron paramagnetic resonance method

Herein, has been presented the results of electron paramagnetic resonance investigations in irradiated and non-irradiated petroleum oils from platform 8, Guneshli oil fields. Free radicals in nonirradiated and irradiated crude oils were identified and determined EPR spectral parameters. This study demonstrates that the EPR technique is suitably applied to the detection of free radicals in petroleum oil and increasing irradiation dose significantly could not influence the radical concentration. The electron paramagnetic resonance method is presented as an eco-friendly approach for monitoring d-elements in petroleum.
