“…2À is soluble in aqueous media. 16 In this work it has also been noted that in the case of using ammonia buffer as the supporting electrolyte, Pb(II) ions can be easily stabilized in the form of a complex such as Pb(II)-tartrate, so 0.02 mol L À1 potassium sodium tartrate was added to the voltammetric cell. The highest and well-dened OA (Fig.…”

“…Most lm electrodes are constructed of silver rod, glass carbon or carbon paste etc. that are covered with bismuth, lead, gallium or mercury [33][34][35][36][37][38]. Mercury lm electrodes have been used extensively in stripping voltammetry due to their advantages while only a negligible amount of mercury is used [39,40].…”

In this study, the amalgam zinc film on glassy carbon electrode was obtained in situ deposition; it was used to study the determination of Zn (II). Exceptional sensitivity of the determination was demonstrated using fast scan (v < 1 KV/s) anodic stripping voltammetry. The scan rate of 500 V/s was chosen for subsequent determination. In this condition, the calibration curve of Zn (II) was obtained. The concentration of Zn (II) and the peak current showed a good linear relationship from 1×10− 7 mg / mL to 1×10− 11 mg / mL for Zn (II). The detection limit attained for Zn (II) was estimated up to 3.33×10− 12 mg / mL. In addition, Zn (II) was spiked and determined in samples of deionized water. The recovery values for these experiments were between 105.1% and 93.7%, and their relative standard deviation was 3.9%-6.2%. We demonstrate that the proposed method has potential for practical application in analyses of wastewaters and seawaters due to its good anti-interference ability.

“…Most popular types of film electrodes are constructed of silver rod, covered by bismuth, lead gallium or mercury. [30][31][32][33][34][35][36][37] Especially mercury film electrodes are attractive considering mercury parameters and its lower amount of waste generated during measurements in comparison with classical mercury drop electrodes. Renewable mercury film silver based electrode (Hg(Ag)FE) 38 is widely used for organic and inorganic compounds determination with low detection limits.…”

A novel high sensitive method of drospirenone (DR) voltammetric determination was successfully developed for the first time. In order to provide repeatability and low limit of detection, mercury film silver based electrode (Hg(Ag)FE) was applied as the working electrode. The electrochemical behavior of drospirenone reduction on Hg(Ag)FE was investigated using cyclic voltammetry. A linear voltammetric response was obtained for analyte in the concentration range from 2.50·10−9 mol L−1 (9.16·10−7 g L−1) to 1.00·10−8 mol L−1 (3.66·10−6 g L−1), with a detection limit of 1.7·10−9 mol L−1 for preconcentration time of 60 s. Repeatability of method was determined as RSD % for drospirenone concentration of 0.05·10−6 mol L−1 as 1.5% (n = 8). The proposed method was successfully applied and validated by studying the recovery of drospirenone in commercially available combined oral contraceptive pills.
