摘要：

The use of the L'vov platform as an electrode for electrodeposition and the subsequent determination of Cd by electrothermal atomisation atomic absorption spectrometry are described. A preliminary electroanalytical study of the L'vov platform as a cathodic macro-electrode for the pre-concentration of Cd (amalgamated on a mercury film) has been carried out. After the film had been formed, the platform was transferred into a graphite tube to atomise the element. The reliability of the method was tested for the determination of Cd; the method was found to be highly sensitive due to the electroanalytical step.
