Voltammetric determination and speciation of inorganic and organometallic tin

The voltammetric determination of chemical forms of tin was investigated. Attention was focused on inorganic Sn(II) and Sn(IV), and on the organometallic species dibutyltin dichloride and tributyltin chloride. The effects of supporting electrolyte, the waveform and the scan parameters upon the analytical signal were studied. Conditions for the simultaneous or sequential determination of the four species, when feasible, were identified
