Abstract
The prepared polymeric resin displayed good figures of merits with analytical calibration curve ranging from 1 to 120 μg Lâ1 for copper and 2 to 100 μg Lâ1 for lead ions with limits of detection of 0.4 μg Lâ1 for copper and 0.9 μg Lâ1 for lead, adsorption capacities of 84 and 110 mg gâ1 for copper and lead ions, respectively, extraction efficiency of greater than 96%, and relative standard deviation (RSD) of less than 4% for eight separate column experiments in determination of 5.0 μg of lead and copper. The obtained data for adsorption capacity of the sorbent shows the high tendency of the sorbent toward the mentioned ions in this nanostructure form. Finally, this sorbent can be used as a simple, rapid, reliable, selective and sensitive method for determination of trace levels of Cu(II) and Pb(II).
