Abstract
A highly sensitive and selective spectrophotometric method for the det ermination of palladium has been worked out in neutral medium utilizin g thiosalicylic acid as a ligand. The coloured metal complex thus obta ined is quantitatively extractable into chloroform in the presence of hexylamine. The method is free from the interference of a large number of metal ions including platinum metals. The ratio of metal to ligand in the extracted species is 1:2. The standard deviation is +/- 0.002.
