In the present work, poly(aryl ether ketone) containing pendant carboxyl groups (PEK-L) is prepared to develop efficient adsorbent for heavy metal ions, Cu(II), Pb(II), Co(II), Ni(II), and Cd(II), from aqueous solution. The property of PEK-L is investigated by using FT-IR and XRD analysis. Effects o...
