| pubmed-article:19609031 | pubmed:abstractText | The applicability of 2-hydroxybenzaldehyde benzoylhydrazone (2-HBBH) for determining Cd(II), Cu(II), Pb(II) and Bi(III) ions by adsorptive cathodic stripping voltammetry was studied. The sensitivity of metal reduction peak currents was highly enhanced with the addition of 2-HBBH to metallic solutions, showing the adsorptive characteristics of the complexes. Variable factors affecting the response (mainly: the influences of pH, supporting electrolyte and deposition potential on selectivity and sensitivity) were investigated. Limits of detection suitable for trace analysis were obtained: 0.28 microg L(-1) for Cd(II) at pH 10; 0.026 microg L(-1) for Pb(II) at pH 9; 0.285 microg L(-1) for Bi(III) at pH 8 and 0.051 microg L(-1) for Cu(II) at pH 9.5. Simultaneous determinations of two groups of elements, consisting of Cd(II)-Pb(II)-Cu(II) and Cd(II)-Pb(II)-Bi(III), at pH 9.5 and 9, respectively, were described with good resolution and sensitivities. Metals were quantified at concentrations in the range from 0.5 to 14 microg L(-1). The RSD at a concentration level of 5 microg L(-1) of metal was 4.28% for Cd(II), 2.99% for Pb(II), 4.82% for Bi(III) and 1.35% for Cu(II). The method was applied to the simultaneous determination of metals in certified reference water (TMDA-62) and in synthetic water samples with satisfactory results. | lld:pubmed |
