Impact of polyhexamethylene guanidine on filtering of Pb(II) and Cd(II) hydroxides from aqueous solutions

Аннотация

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.
