Özet

Fe(II), Sr(II) and Cu(II) ions were enriched and removed simultaneously using benzenesulfonic acid-1-methyl hydrazide (BSMH) on activated carbon (AC) in aqua solution. However, only Cu(II) ions were pre-concentrated and removed by using N-(3-amino-2-hydroxypropyl) benzenesulfonamide (BSDIAP). Adsorbed metals were enriched 10-fold and determined by ICP-OES. Interferences of Ca, Mg and K were also investigated. The proposed method was applied to tap water and creek water of Ankara. It also provides the removal of Cu, Fe and Sr by 99, 97 and 95% removal from water, respectively. Detection limits of ions were 0.34 mu g/L for Fe, 0.29 mu g/L for Cu and 0.36 mu g/L for Sr with BSMH ligand but 0.32 mu g/L for Cu with BSDIAP ligand. In addition, the computation of some physicochemical properties has shown good correlation between the recoveries and removals of metals.
