中文摘要	Potentiometric sensors have been exploited for the determination of Hg2+ ions. However, applications of such sensors are limited to mercury detection in the absence of a Cl--rich background since Hg2+ can readily form coordination complexes with Cl-. This paper describes a potentiometric sensor for the determination of anionic mercury species using tert-butylcalix[4] arene-tetrakis(N, N-dimethylthioacetamide) as anion-selective ionophore and tridodecylmethylammonium chloride as ion exchanger. An asymmetric membrane rotating ion-selective electrode configuration is used to improve the detection sensitivity. By using HgCl3-as a model of anionic mercury species, the proposed method allows potentiometric detection of mercury down to nanomolar levels in samples containing 0.05 M NaCl background electrolyte. The practical application of the proposed sensor has been performed for the determination of total mercury concentrations in diluted seawater samples. (C) 2014 Elsevier B.V. All rights reserved.
