B. Pradeep Raju | N. Devanna ^[3]

Abstract: An alpha Amyl Cinnamaldehyde Isonicotinoyl Hydrazone (ACINH) is newly synthesised novel chromogenic reagent, ACINH is used for the determination of Cd (II) by a spectrophotometric method. ACINH forms a yellow coloured water soluble [Cd (II) -ACINH] complex with Cd (II) in the pH range 9.0. At max 380 nm the complexes shows maximum absorbance and at pH range 9.0. Hence further analytical studies were carried out at max 380 nm. Beers law is obeyed in the range of 0.5031-5.0531 g/ml Cd (II). The molar absorptivity and sandells sensitivity of the complex are 2.94x104 L. mol-1. cm-1 & 0.0034 g/cm2 respectively. Cd (II) forms metal ligand ratio as 11 complex with ACINH and complex shows stability constant 8.58x107 was obtained by jobs method. The tolerance limits of various foreign ions have also been studied. For the determination of Cd (II) newly developed derivative spectrophotometric method has been employed and good analytical results in soil samples.
