Abstract

An electrochemistry sensor composed of glass carbon electrode modified with [ZnSO4{ZnCl2(u-S-CH2CH2NH2}]n was used for the determination of mercury(II) ions with differential pulse voltammetry(DPV) in 0.1mol/L KCl solutions. The proposed electrochemistry sensor had good operating characteristics towards Hg2+, including a relatively good selectivity, the response to Hg(II) ions in a concentration range of 1.8×10-5 to 4.5×10-4 mol/L, and the corresponding linear regression aquation was I=-0.2234C-1E-05, the correlation coefficient was 0.9970, the detection limit was 0.1umol/L. Modified electrode was verified through the experiment of standard addition analysis application in water samples with a recovery rate of 95.12% 102.58%. Additionally, some common metal ions (Mg2+ Mn2+ Zn2+) had no obvious effects on the determination of Hg2+.
