title: Potentiometric determination of n-butyl-1-biguanide with a liquid-state Cu2+-sensitive electrode.
abstract: Alkyl-1-biguanides are determined by titration with copper(II), or excess of copper(II) is added and the surplus determined by titration with EDTA, a liquid-state copper-sensitive electrode being used in both cases for potentiometric detection of the end-point.
