Abstract
The prepared polymeric resin displayed good figures of merits with analytical calibration curve ranging from 1 to 120 μg L−1 for copper and 2 to 100 μg L−1 for lead ions with limits of detection of 0.4 μg L−1 for copper and 0.9 μg L−1 for lead, adsorption capacities of 84 and 110 mg g−1 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).
