A Study on the Simultaneous Determination of Copper and Tin in the Presence of Lead
摘要:
A very sensitive electrochemical procedure for trace determination of copper and tin in the presence of lead using cathodic adsorption voltammetry is presented. The complex of copper, tin with salicylfluorone (SAF) is adsorbed on the hanging mercury drop electrode (HMDE) and the reduction current of the accumulated complex is measured by voltammetry. This method achieves the simultaneous determination of copper and tin, and has been applied to determine canned food.
