DEGRADED PET FOR THE REMOVAL OF METAL IONS FROM AQUEOUS SOLUTION

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, H¹NMR, DSC, and GPC, being identified as bis(2-...
