“…Cu(II), Ni(II), Co(II), Zn(II), Pb(II) ions were effectively removed by the strongly (Lewatit MonoPlus M500, Lewatit MonoPlus MP 500 [ 45 ], Amberlite IRA458, Amberlite IRA958 [ 46 , 47 ], Amberlite IRA 402 [ 47 ], Amberlite IRA402 [ 48 ]) and weakly basic (Amberlite IRA67 [ 46 ]) anion exchange resins in the presence of various complexing agents. Our previous studies concerning Co(II), Ni(II), Cu(II) and Zn(II) removal on the weakly (Purolite A830, Lewatit MonoPlusTP220), intermediate (Amberlite IRA478RF) and strongly (Dowex MSA1, Dowex MSA2, Lewatit MonoPlus SR7, Purolite A400TL) basic anion exchangers, as well as the chelating (Purolite S984) and carbon-based (Lewatit AF5) adsorbent showed that the highest capacity was obtained for the resin of bis-picolyamine functional groups [ 49 , 50 , 51 , 52 , 53 , 54 , 55 ].…”
