Abstract
A solvent extraction separation method for determination of tin(II) ha s been described. Tin(II) is extracted from an aqueous solution of pH 2.15-2.60 with a solution of Cyanex 302 in toluene. It is stripped fro m toluene into 0.75-1.50 mol dm(-3) perchloric acid and estimated spec trophotometrically with pyrocatechol violet. The molar absorptivity of the tin(II)- Cyanex 302 complex in toluene is 6.5x10(4) at 555 nm. Th e method has been applied for the determination of tin(II) in alloys a nd canned food stuffs.
