A new spectrophotometric determination of tin was investigated. Stannic ion formed a colored complex with alizarine blue in 1 N-HCl solution and was extracted by the mixed solution of cyclohexanone and ethyl acetate. This complex had a maximum absorption at the wave length of 580 mμ, and its molecular absorption coefficient was 9.5×103. This reaction was also applied to the determination of tin in steel after its separation with hydrogen sulfide. Similarly in the case of nonferrous alloys, 0.001 to 0.1% of tin was analyzed after being separated by co-precipitation with manganese dioxide.
