The reactions of pentacyanoferrate(II) ions-iv spectrophotometric study, detection and determination of Toxogonine.
The interaction of Toxogonine with ammine- and nitrosyl-pentacyanoferrate(II) ions has been studied spectrophotometrically under different reaction conditions. The same reactions were the basis for specific spot-tests and new simple and rapid spectrophotometric methods for the determination of Toxogonine in the range 15-85 or 15-150 mug/ml. From the calibration curves the molar absorptivities of the complexes were calculated and the proposed methods tested for the determination of Toxogonine in pharmaceutical preparations.
