Overview

Randomized trial demonstrates high sensitivity for detecting Hg2+ in water, suggesting improved safety standards.

Key Points

  • This research aims to develop a highly sensitive electrochemical sensor for detecting inorganic mercury ions (Hg2+) in water.
  • Iron phthalocyanine (FePc) was anchored onto MXene to create a heterostructure.
  • The F/M composite was modified onto a glassy carbon electrode for testing.
  • Detection performance was evaluated using square-wave anodic stripping voltammetry under optimized conditions.
  • The sensor exhibited a linear range of 0.1–1.0 μM for Hg2+ detection and a sensitivity of 19.02 μA/μM.
  • It demonstrated a low detection limit of 5.9 nM with good anti-interference against other metal ions.
  • Batch-to-batch and long-term stability were confirmed with RSD values of 2.03% and 2.49%, respectively.
