Sorption behavior of environmentally relevant metal cations of 4-vinylpyridine based resins

SummarySorption behavior of resins based on 4-vinylpyridine and N,N′-dimethylacrylamide and 2-acrylamidoglycolic acid as comonomers, compared with the crosslinked homopolymers, towards Hg(II), Cd(II), Zn(II), Pb(II), and Cr(III) was studied at different pHs depending on the metal ion. Some resins sh...

Zusammenfassung:	SummarySorption behavior of resins based on 4-vinylpyridine and N,N′-dimethylacrylamide and 2-acrylamidoglycolic acid as comonomers, compared with the crosslinked homopolymers, towards Hg(II), Cd(II), Zn(II), Pb(II), and Cr(III) was studied at different pHs depending on the metal ion. Some resins show that from pH = 1.0 or 2.0 Hg(II), Cr(III), and Cd(II) were sorbed significatively from an aqueous solution of 1.0 g/L. Hg(II) and Cr(III) were eluted significatively in acidic media.
