Abstract

PREPARATION AND IDENTIFICATION OF NEW ORGANIC REAGENT 2-{(6-MTHYL BENZOTHIAZOL AZO) -1- NAPHTHOL -4- SULFONIC} AND USE IT IN DETERMINATION FOR COPPER ION BY FLOW INJECTION TECHNIQUES

Haider Norri Raheem*

ABSTRACT

The research includes preparation and identification of new aza reagent 2-{(6-mthyl benzothiazol azo) -1- naphthol -4-sulfonic} by infrared (FTIR), spectrophotometric Uv- vis, melting point. This reagent used for estimation copper (II) in new design of (FIA) system, the various parameters (chemical and physical) affecting on estimation have been investigated such as flow rate was 9 ml/min, reaction coil 35 cm, volume reagent 335.5 μl, volume sample 196.25. μl, pH was 7 and reagent concentration 10-4 M, after that preparation the calibration curve in flow injection analysis system, the average desperation coefficient was 1.117 and reliability were studied. Compared between two methods (spectrophotometric method and FIA method).

Keywords: Copper ion, Determination, Flow Injection.
