An Amperometric Sensor for the Selective Determination of Ortho-Diphenols in Olive Oil

摘要

An electrochemical flow injection analysis method for the selective determination of ortho-diphenols have been developed and optimized. The method is based on the use of sodium molybdate as an electrochemical mediator. The selectivity of the measurement has been evaluated with respect to different ortho-diphenols and phenols that are usually found in extra-virgin olive oil. After FIA optimization the protocol has been applied to the detection of olive oil samples and results were compared with a reference method.
