A novel electrochemical displacement sensor has been reported for the first time standing on the oxidation behavior of the modifier and displacer. The electrochemical displacement sensor based on glassy carbon electrode (GC) modified with natural latex-capped silver nanoparticles (NL-AgNPs) has been conducted for the Eriochrome Black T (EBT) assessment. NL-AgNPs have been synthesized by direct chemical reduction under different reaction conditions such as NL and AgNO3 concentration, temperature and pH for optimizing the size, and stability of nanoparticles before modifying the GC electrode. Under the optimized conditions, NL-AgNPs have been characterized with UV–VIS spectroscopy, fluorescence emission spectroscopy (FL), transmission electron microscope (TEM), zeta potential analyzer and cyclic voltammetry (CV). Under optimized electrolytic and voltammetric conditions, EBT has been detected at NL-AgNPs/GC based on modifier (NL-AgNPs) and displacer (EBT) oxidation. Both displacer and modifier-based sensor (two-way sensor) have shown a linear range of 2–96 µg/L and detection limits of 2.92 and 7.01 µg/L, respectively. A high selectivity for EBT detection in river water with 110 and 107.5 recovery values has been shown for both modifier- and displacer-based sensor, respectively.
