“…It is known that in a weak acidic medium, 4-tert-octylphenol is irreversibly oxidized in a one electron transfer process (n = 1) instead of a two-electron process which take place in basic medium. 63,64,67 The determination of 4-tert-octylphenol at the Clay/CPE was performed by using cyclic (CV) and square wave voltammetry (SQW). The results are presented in Figure 8.…”

A simple and sensitive electroanalytical method was developed to determine the Endocrine Disrupting chemical 4-tert-octylphenol on clay modified carbon paste electrode (Clay/CPE). The electrochemical response of the proposed electrode was studied by means of cyclic and square wave voltammetry. The structural morphology of the modified electrode was characterized by SEM/EDX and XRD techniques. It has been found that the oxidation of 4-tert-octylphenol on the clay/CPE displayed a well-defined oxidation peak. Factors influencing the detection processes were optimized. 4-tert-octylphenoloxidation occurred through a surface process involving its adsorption on the clay/CPE. Under these optimal conditions, a linear relation between concentrations of 4-tert-octylphenoland current response was obtained over the range of 7.26 × 10 −6 to 3.87 × 10 −7 with a detection limit and a quantification limit of 9.2 × 10 −7 M and 3.06 × 10 −6 M, respectively. The correlation coefficient is 0.9963. The modified electrode showed suitable sensitivity, high stability and an accurate detection of 4-tert-octylphenol.The modified electrode also relevant suitable selectivity for various phenolic estrogenic compounds such as 4-Nonylphenol and Bisphenol A.
