“…The voltammetric method was firstly used to determine the concentration of Cd and Pb in seawater (Neeb 1959). Recently, anodic stripping voltammetry was also used to this purpose (Zirino et al 1973;Abdullah et al 1976;Gillain et al 1979;Jurado-Gonzelez et al 2003;Van den Berg 1986).…”

In this work, the heavy metals cadmium and lead in Kepez harbor were studied with regard to the determination of the environmental pollution levels. Seawater samples of the Dardanelles (Canakkale Strait) were collected from the nearest station to Kepez harbor in July 2007. Then, the concentrations of these metals were determined after simple pretreatment of samples by the proposed inductively coupled plasma-atomic emission spectrometry (ICP-AES) method. The analysis of a given sample is completed in about 15 min by the ICP-AES method, and the concentrations of Cd and Pb were found to be 73.80 mg L(-1) (relative standard deviation [RSD], 1.07%) and 9.39 mg L(-1) (RSD, 0.70%), respectively. The accuracy of the applied ICP technique was checked by recovery studies, and good recoveries were obtained. The pollution levels of Cd and Pb recorded in this study were compared with those in other studies to analyze the water sample in Kepez harbor.

Cadmium and lead were determined simultaneously in seawater by differential pulse stripping voltammetry (DPSV) preceded by adsoptive collection of complexes with 8-hydroxyquinoline (oxine) on to a hanging mercury drop electrode (HMDE). In preliminary experiments the optimal analytical condition for oxine concentration was found to be 2.10(-5) M, at pH 7.7, the accumulation potential was -1.1 V, and the initial scannig potential was -0.8 V. The peak potentials were found -0.652 V for Cd and -0.463 V for Pb At the 60 s accumalation time. The limit of detection (LOD) and limit of quantitatification (LOQ) were found to be by voltammetry as 0.588 and 1.959 microg l(-1) (RSD, 5.50%) for Cd and 0.931 and 3.104 microg l(-1) (RSD, 4.10%) for Pb at 60 s stirred accumulation time respectively. In these conditions the most of the seawater samples are amenable for direct voltammetric determination of cadmium and lead using a HMDE. An adsorptive stripping mechanism of the electrode reaction was proposed. For the comparison, seawater samples were also analysed by ICP-atomic emission spectrometry method (ICP-AES). The applied voltammetric technique was validated and good recoveries were obtained.

“…However, the conventional MFE suffers strongly from the presence of surfactants, which affect both the peak current and the peak potential and can also yield tensammetric peaks [1,2,6,7]. Also, the mechanical stability of ex situ thin mercury films, used throughout several determinations with the exchange of sample solutions may become a severe problem due to the coalescence of the mercury microdroplets and consequent patchiness in the texture of the film [8]. The use of chemically modified electrodes (CMEs) in the analysis of complex matrix samples [2,9,10] minimize these problems.…”

Performance of Poly(styrenesulfonate)‐Coated Thin Mercury Film Electrodes in the Determination of Lead and Copper in Estuarine Water Samples of High Salinity

Thin mercury film electrodes coated with poly(styrenesulfonate) (PSS-TMFE) were prepared by solvent evaporation of an aqueous solution of the polymer onto a glassy carbon electrode followed by electrolytic deposition of the mercury film through the polymer layer. The performance of these polymer modified mercury film electrodes is evaluated in a NaCl solution using lead(II) as a model heavy metal cation. This new methodology presents an improved sensitivity, mechanical stability, reproducibility, repeatibility and increased efficiency against surfactants when comparing to the conventional TMFE. Square-wave anodic stripping voltammetry at the ex situ mercury plated PSS-TMFE was successfully applied to the determination of total and labile amounts of lead and copper in estuarine water samples of variable and high salinity (23.5Ω ± 35.0Ω). Concentrations in the nanomolar region can be easily assessed using a 3 minutes accumulation time with low relative standard deviations (less than 3%).
