摘要
The electrophoretic behavior of polyhexamethyleneguanidine hydrochloride (PHMG HC), hexamethylenediamine (HMDA), and guanidine hydrochloride (GHC) was studied. It was shown that PHMG HC and the initial toxic components of its synthesis, GMDA and GHC, can be separated. A procedure was developed for determining PHMG HC oligomers, GMDA, and GHC in aqueous solutions in concentrations from 0.007 to 0.05 mg/mL by capillary electrophoresis. The procedure was applied to the analysis of model mixtures of these compounds.
