title: Analytical determination of dimethyl sulphoxide by complex formation with the pentacyanoferrate(II) ion.
abstract: A method for determination of small amounts of dimethyl sulphoxide and non-hindered sulphoxides is proposed, based on selective reaction with the aquapentacyanoferrate(II) ion, leading to stable complexes which can be detected electrochemically.
