A glassy carbon electrode coated the film of 4‐tert‐butyl‐1‐(ethoxycarbonylmethoxy)thiacalix[4]arene is designed for the determination of trace amounts of Hg 2+ . Compared with bare glassy carbon electrode, the modified electrode can improve the measuring sensitivity of Hg 2+ . Under the optimum experimental condition, the modified electrode in 0.1 mol L −1 H 2 SO 4 + 0.01 mol L −1 KCl solution shows a linear voltammetric response in the range of 8.0 × 10 −9 ∼ 3.0 × 10 −6 mol L −1 with detection limit 5.0 × 10 −9 mol L −1 for Hg 2+ . The high sensitivity, selectivity, and stability of modified electrode also prove its practical application for a simple, rapid and economical determination of Hg 2+ in water samples.
