Extraction of Palladium- [4-(2-Thiazolylazo)Resorcinol] Complexes and Spectrophotometric Determination of Palladium

The extraction of palladium(II) as a red camples with 4-(2- -thiazolylazo)resarciinol (TAR = H2R) by tetraphenylphasphanium chloride in chloroform was studied. Quantitative extraction was achieved in the pH region between 2 and 10. By extraction at pH 2 and by spectrophotometric measurements of the...

Summary:The extraction of palladium(II) as a red camples with 4-(2- -thiazolylazo)resarciinol (TAR = H2R) by tetraphenylphasphanium chloride in chloroform was studied. Quantitative extraction was achieved in the pH region between 2 and 10. By extraction at pH 2 and by spectrophotometric measurements of the red complex in the organic phase, a sensitive and selective method for palladium determination was evaluated. An anionic complex [PdRCl]" was predominantly extracted over a wide pH range forming ion associates with tetraphenylphasphomium cation 0Lax = 525 . nm, s = 2.4 X 104 1 mol1 cm"1). The extracted complexes were studied in solution and by characterization of the isolated solid compounds
