Determination of Biguanide Groups in Polyhexamethylene Biguanide Hydrochloride by Titrimetric Methods

Analytical Sciences, 2003
The biguanide concentration of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was measured by non-aqueous titration with HClO4, argentometric titration, the Kjeldhal method, and colloidal titration. The summation value of non-aqueous titration and argentometric titration corresponded to two titrable nitrogens in five nitrogens per one unit of ...
