A flow injection analysis (FIA) incorporating a thiosemicarbazone-based coated wire electrode (CWE) was developed method for the determination of mercury(II). A 0.1 M KNO(3) carrier stream with pH between 1 and 5 and flow rate of 1 mL·min(-1) were used as optimum parameters. A linear plot within the concentration range of 5 × 10(-6)–0.1 M Hg(II), slope of 27.8 ± 1 mV per decade and correlation coefficient (R2) of 0.984 were obtained. The system was successfully applied for the determination of mercury(II) in dental amalgam solutions and spiked environmental water samples. Highly reproducible measurements with relative standard deviation (RSD < 1% (n = 3)) were obtained, giving a typical throughput of 30 samples·h(-1).
一种基于硫代氨基甲酸盐的涂丝电极（CWE）的流动注射分析（FIA）方法被开发用于测定汞（II）。使用 0.1 M KNO3 载体流，pH 值在 1 到 5 之间，流速为 1 mL·min(-1)，作为最佳参数。在浓度范围为 5×10(-6)到 0.1 M Hg(II)之间，获得了 27.8 ± 1 mV 每 decade 的斜率和 0.984 的相关系数（R2）的线性图。该系统成功地应用于牙科汞合金溶液和加标环境水样中汞（II）的测定。相对标准偏差（RSD < 1%（n = 3））的测量结果高度重现，典型的吞吐量为 30 个样品·h(-1)。
