Abstract

The Schiff bases are formed by condensation of different β-diketones, salicylaldehydes or 2-hydroxyacetophenes with various amines. These bases react with metal and oxo-metal cations to form stable metal chelates which absorb/fluoresce in UV or visible region of light. The Schiff bases have been used in the determination of metal ions by spectrophotometry, spectrofluorimetry, gas chromatography, liquid chromatography and capillary electrophoresis. Ion-selective electrodes using Schiff’s bases is an emerging area for metal ion analysis. This review covers brief synthesis, chelation properties and analytical applications of Schiff bases.
