A simple and sensitive spectrophotometric method has been developed for the determination of palladium(II) using
newly synthesized 3-methoxysalcilaldehyde-4-hydroxybenzoylhydrazone (MSHBH) reagent in a micellar medium of
CTAB (acidic surfactant). Palladium(II) forms an orange yellow colored water soluble complex with the MSHBH
reagent in acidic buffer medium pH 4.5. Beer�¢����s law obeyed in the range 0.2876 to 4.2568 �Ž�¼g/mL of Pd(II) �Ž�»max at
412 nm. The molar absorptivity and Sandell�¢����s sensitivity of colored species are 1.03 x104 L.mol-1.cm-1 and 0.0103
�Ž�¼g.cm-2 respectively. Palladium(II) forms (M: L) 1:1 complex and stability constant of the complex is 9.32x104. The
developed first and second order derivative spectrophotometric methods were employed for the determination of
palladium(II) in alloy samples and hydrogenation catalyst samples.
