4DescriptionAbstract A non-extractive spectrophotometric method is developed for the trace determination of tin(II). The method involves the formation of yellow (1:2) coloured complex 5,7-dibromo-8-hydroxyquinoline (DBHQ) in slightly acidic medium. The complex is in aqueous medium (water and ethanol solution) show absorbance at 393 nm. The complex is stable up to 4 days. Beers law obeyed in the range of 0-9.0 μg Sn mL-1, molar absorptivity, specific absorptivity and Sandells sensitivity of complex are 8.133x104 L mol-1cm-1, 0.4291 mL g-1cm-1 and 0.00233 μg cm-2 at 393 nm. Potential interferences have been studied. The method is free from interferences of large number of metal ions such as Hg, Co, Mo, Se, Bi, Cd, V, Re, Ce, W, Ag, Ca, Be, U, Pt, Ti and other analytically important metals and anions /complexing agents. The method is quite simple, highly selective and sensitive with good reproductibility and not required any solvents for extraction. The method has been satisfactorily, by utilizing the proposed procedure; its applicability has been tested by the analysis of synthetic samples and an alloys sample of gun metal. The procedure assumes in view of the scarcity of better method for the determining tin. The results are in good agreement with certified value.
