Simple potentiometry and cyclic voltammetry techniques for sensing Hg ions in water using a promising flower-shaped WS-WO/poly-2-aminobenzene-1-thiol nanocomposite thin film electrode.

A highly promising flower-shaped WS-WO/poly-2-aminobenzene-1-thiol (P2ABT) nanocomposite was successfully synthesized a reaction involving 2-aminobenzene-1-thiol, NaWO, and KSO as oxidants. The WS-WO/P2ABT nanocomposite demonstrated remarkable potential as a sensor for detecting harmful Hg ions in aqueous solutions. The sensing behavior was evaluated over a wide concentration range, from 10 to 10 M, using a simple potentiometric study on a two-electrode cell.
