    Electrochemical Detection of Cadmium and Lead Complexes with Low Molecular Weight Organic Acids

  • Original language description

    The Cd and Pb complexes with oxalic (OA) and citric acid (CA) were detected in model and soil solutions using cyclic and stripping voltammetry. A mixed complex consisting of Cd, Pb, and OA was found; its peak potential varied from -582.0 to -542.5 mV (vs. Ag/AgCl/KCl(3 mol/L)). For mixed complex formation, the presence of PbOH+ species and Cd2+ in oxalic acid solution was necessary. Only the "simple" complexes of CA with Pb and Cd were found in the model solution. The existence of all investigated metalcomplexes is confined to neutral pH range. The mixed komplex was also found in real soil solutions.

    Elektrochemická detekce komplexů kadmia a olova s nízkomolekulárními organickými kyselinami

  • Czech description

    Komplexy Cd a Pb s kyselinou šťavelovou (OA) a citrónovou (CA) byly detekovány v modelových a půdních roztocích při užití cyklické a rozpouštěcí voltametrie. Byl nalezen směsný komplex sestávající z Cd, Pb, a OA; potenciál jeho píku se pohyboval od -582.0 do -542.5 mV (vs. Ag/AgCl/KCl(3 mol/L)). Pro tvorbu směsného komplexu je nezbytná přítomnost PbOH+ a Cd2+ v roztoku kyseliny šťavelové. V modelových roztocích byly nalezeny pouze "jednoduché" komplexy CA s Pb a Cd. Existence všech zkoumaných komplexů kovů je omezena na neutrální oblast pH. Směsný komplex byl nalezen též v reálných půdních roztocích.
