|
The electrochemical behaviors and analytical application of copper-1,5,9,13-tetrathiacyclohexadecane[16-ane-S4] complex in acetonitrile(AN) solution have been investigated by the use of DC polarography and differential pulse polarography. Thus the formation constant of copper complex was 103.51. Copper (Ⅱ) ion was found to form complex of 1-to-1 composition with [16-ane-S4]. In addition, reduction step was irreversible and the reduction current was diffusion controlled. And the effect of concentration of the salting-out reagent and chelating agent and pH of aqueous phase on the determination of copper (Ⅱ) was investigated and diverse ion effect was discussed. By salting-out extraction technique, we can be determined until the concentration of copper (Ⅱ) of 60 ppb.
