Spectrophotometric determination of palladium(II) using 2-cis 3, 7 -dimethyl 2,6-octadien-1-oxime

Department of Chemistry, University of Rajasthan, Jaipur-302 004, India Manuscript received 6 August 2002, revised 12 March 2003, accepted 17 March 2003 2-cis 3,7-Dimethyl 2,6-octadien-1-oxime forms a 1 : 2 (Pd : CDOO) red coloured complex at 47-57" in 0.03-0.14 M CH3COOH medium which is extracted into chloroform having λmax at 445 nm. The molar absorptivity, Sandell's sensitivity and standard deviations are 2.434 x 103 dm3 mol-1 cm-1, 0.0007 mg cm-2 and ±0.0012 absorbance unit respectively. Beer's law is obeyed over the concentration range 0.4-40.0 \(\mu\)g/ml of PdII. Presence of a large number of elements do not interfere. The method has good reproducibility and can be satisfactorily applied for the analysis of industrial samples
