Gold-copper film electrode prepared in situ on carbon paste solid disk substrate (Au–CuF/CPE) was studied as a working electrode. The factors influencing mercury stripping peak currents, such as (0.20 mg/L), (0.05 mg/L), type of acids and their concentration (HClO₄, 0.005 M), deposition potential (-800 mV) for Au–CuF/CPE, deposition time (180 s), and interferents, were investigated and optimized. The method has a low limit of detection of 0.13 μg/L and is not affected significantly by the examined ions/substance. It was applied to detect the concentration of Hg in real water samples and is promising for practical usage.

用于伏安法测定水中汞的金铜膜电极

研究了在碳糊固体圆盘基底（Au-CuF/CPE）上原位制备的金铜膜电极作为工作电极。影响汞汽提峰值电流的因素，例如(0.20 mg/L)、(0.05 mg/L)、酸的类型及其浓度 (HClO ₄ , 0.005 M)、Au-CuF/的沉积电位 (-800 mV)研究并优化了 CPE、沉积时间 (180 秒) 和干扰物。该方法的检测下限为 0.13  μ g/L，并且不受被检离子/物质的显着影响。已应用于实际水样中汞浓度的检测，具有实际应用前景。
