Abstract

Covalent bonding of polyhexamethyleneguanidine amides of maleic and o-phthalic acids to the aminated silica surface was performed. The complexing properties of the obtained composite adsorbents with respect to Zn(II), Cu(II), Fe(III), Co(II), Pb(II), Ni(II), Mn(II), Mo(VI), and Cr(VI) ions were studied. The Mo(VI) and Cr(VI) reduction was detected on the modified silica surface bearing polyhexamethyleneguanidine amide with o-phthalic acid. The formation of different-ligand complexes with transition metal cations adsorbed on the synthesized composite surface was studied.

Abstract

The possibility was determined for covalent binding of amide of maleic acid and polyhexamethyleneguanidine to a silica gel surface previously activated with cyanur chloride. Adsorption of Zn(II), Cd(II), Pb(II), Cu(II), Mn(II), Ni(II), Fe(III), and Co(II) cations from aqueous solution with a modified silica obtained was studied. The possibility of subsequent formation on the surface of mixed ligand complexes
