説明

The electrochemical behavior of tributyltin (IV) chloride in 20% (v/v) methanol-water medium at the trace level has been investigated by differential pulse anodic stripping voltammetry with a bare glassy carbon (GC) electrode and a binuclear ruthenium complex, (μ-1,1,6,6-tetraacetyl-2,4-hexadiynato) bis[bis (2,2,6,6-tetramethyl-1,3-heptanedionato) ruthenium (III)], coated GC electrode. The tin compound exhibited an anodic peak at -0.70 V vs. Ag/AgCl on the voltammogram with the coated electrode, but the corresponding peak was not observed with the bare electrode. This is the first example of detection for organotin compounds by voltammetric methods without an Hg electrode.
