The paper presents results of investigations aimed at optimizing the process of Pb(II) and Cd(II) removal using polyhexamethylene guanidine (PHMG) from aqueous solutions. The formation of compounds of chemisorption-type ions of the above metals with PHMG was established by using the methods of polarography, infrared spectroscopy, and pH-metry. The investigations revealed a positive impact of PHMG on the sedimentation and filtering of the precipitation of Pb(II) and Cd(II) hydroxides.
