“…Although the detection limit of other Hg(II) ISE in FIA systems [23,29] are relatively the same as that obtained with the proposed mercury(II) ISE, the latter has a wider linear range (Table 4). …”

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 KNO3 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.

“…Potentiometric determination of mercury by using diazacrownionophore membrane electrode has been reported (Yang, et al, 1997;Yang, et al, 1998). Potentiometric device with ISE by incorporation of ionophore in membrane electrode is a robust analytical method for the determination of mercury.…”

The development of mercury ion selective electrode (ISE-Hg) by using ionophore 7,16-Di-(2-methylquinolyl)-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane (DQDC) in an electrode membrane sensing is explained. The study is aimed to construct an ion selective electrode for mercury by immobilization of ionophore DQDC in a polymeric PVC membrane electrode. Membrane electrode was constructed by casting and spin coated methods from the mixture of DQDC and plastisizer in a polymeric PVC matrix dissolved in a tetrahydofuran solvent. The membrane has been characterized and used as a sensing material in an ISE-Hg. The developed ISE-Hggive sensitive and selective response to mercury, working range linearity lies between 0.005 mM -1.0 mM Hg 2+ , slope 25.82 mV per decade concentration of Hg 2+ (r 2 = 0.998).

“…Furthermore, there are few reports on the use of the ISE, with flexible PVC membranes, in flow injection analysis (FIA). In fact, the reproducibility of signals and the electrode lifetime is much better in batch analysis [13]. On the other hand, there are no constraints in using the quartz piezoelectric membrane coated crystals in FIA, and it is easy to enumerate a series of advantages, as for instance the decrease in response time.…”
