Abstract:Poly(ethylene terephthalate) waste was degraded by glycolysis in order to obtain low molecular weight molecules for the batch removal of Cd(II), Cr(III), Cu(II), Ni(II), and Pb(II) from aqueous solution. The degradation product was characterized by IR, H 1 NMR, DSC, and GPC, being identified as bis(2-hydroxy ethyl) terephthalate (BHET). The results show that metal absorption follows the order Pb(II)>Cd(II)>Ni(II)>Cu(II)>Cr(III). Degraded PET presented an affinity to remove over 75% of lead in solution at pH 4 … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
