Enzymatic electrochemical detection coupled to multivariate calibration for the determination of phenolic compounds in environmental samples

► Its scope will include the following topics: the response of horseradish peroxidase reaction was related to phenolic compounds. ► The electrochemical enzymatic response was obtained by square wave voltammetry. ► Five phenolic compounds in water samples were detected by multivariate calibration. ► Two potential ranges were utilized for phenolic compounds by partial least-squares.
