For the determination of tin(II) traces, an extractive spectrophotometric approach is devised. The applied method serves a powerful tool for determination of tin(II), involves the formation of yellow colored complex among the 6-bromo-3-hydroxy-2-(5-methylfuran-2-yl)-4H-chromen-4-one (BHMF) and tin(II) in 1:2 stiochiometry in a slightly acidic medium (HCl). The complex shows absorbance at 434 nm in respect of the blank reagent. The outcomes of spectral investigation for complexation showed a Beer's range of 0-1.3 µg Sn mL − 1 , molar absorptivity, speci c absorptivity and Sandell's complex sensitivity are 9.291 × 10 4 L mol − 1 cm − 1 , 0.490 mL g − 1 cm − 1 and 0.002040 µg cm − 2 at 434 nm and stable for up to two days.The interferences studyresults showed that this method is free from interferences, when tested with metal ions including Ag,

The outcomes of spectral investigation for complexation showed a Beer’s range of 0-1.3 µg Sn mL− 1, molar absorptivity, specific absorptivity and Sandell’s complex sensitivity are 9.291 × 104 L mol− 1cm− 1, 0.490 mL g− 1cm− 1 and 0.002040 µg cm− 2 at 434 nm and stable for up to two days.The interferences studyresults showed that this method is free from interferences, when tested with metal ions including Ag,Be, Bi, Ca,Cd, Ce, Co,Hg, Mo,Re,Pt, Se,Ti,U,V, W and other common cations, anions, and complexing agents. The method is quite simple, highly selective, and sensitive with good re-producibility. The method has been satisfactorily by utilizing the proposed procedure, and its applicability has been tested by analyzing synthetic samples and an alloy sample of gunmetal. The procedure assumes this because of the scarcity of better methods for determining tin(II). The results are in good agreement with the certified value.
