Synthesis and Characterization of 2- Acetyl Furan Benzoyl Hydrazone and its Applications in the Spectrophotometric Determination of Cu (II)

Abstract

The new chromogenic reagent 2-acetylfuran benzoylhydrazone (AFBH) is synthesised, studied its characteristic properties and applied for the spectrophotometric determination of Copper (II) for the first time. The reagent gives greenish yellow complexes with copper (II) in sodium acetate-acetic acid buffer medium of pH 6.5. The molar absorptivities of copper complex is 2.05 x 104 Lmol-1 cm-1. The colour reactions have been investigated for the micro spectrophotometric determination of copper (II) in aqueous medium and applied for various water and biological samples.
