ABSTRACT:
A simple micelle-mediated extraction and preconcentration spectrophotometeric procedure has been established for quantization of Cu (II) at trace levels. The method is based on the reaction between the proposed novel analytical reagent isonicotinohydroxamic acid (INHA) and Cu (II) at pH 8.0 in borate buffer medium. A green coloured complex formed between Cu (II) and INHA is quantitatively extracted into a small volume of surfactant-rich phase of anionic surfactant, sodium dodecyl sulfate (SDS) after centrifugation and is measured at the optimum wavelength of 800 nm. All variables were studied to optimize the reaction conditions. Regression analysis of Beer’s law plot showed good correlation in concentration range of 0.11-1.02 µg mL-1. The molar absorptivity and detection limit are calculated. The interference effects of the foreign ions have been examined. The proposed procedure has been successfully applied to the analysis of Cu (II) in water samples.
