Abstract

The extractive spectrophotometric determination of palladium(II) using 3,4, 5-trimethoxybenzaldehyde thiosemicarbazone (TBTSC) is discussed in this study. It forms an intense yellow-coloured chloroform-soluble complex with paladium(II) in an acidic medium. The molar absorptivity at 370nm is 8.35x 10^{4} 1. mol^{-1} cm^{-1}. The complex system conformed to Beer's Law up to a concentration limit of 12 ppm. The Sandell's sensitivity was 8. 57 ng. cm^{-2}. The interference of various ions was studied, and palladium(II) in its alloy compositions was analysed.
