In this work, a silica surface chemically modified with [3-(2,2'-dipyridylamine)propyl] groups, named [3-(2,2'-dipyridylamine)propyl]silica (Si-Pr-DPA) was prepared, characterized, and evaluated for its heavy metal adsorption characteristics from aqueous solution. To our knowledge, we are the first authors who have reported the present modification. The material was characterized using infrared spectroscopy, SEM, and NMR (29) Si and (13) C solid state. Batch and column experiments were conducted to investigate for heavy metal removal from dilute aqueous solution by sorption onto Si-Pr-DPA. From a number of studies the affinity of various metal ions for the Si-Pr-DPA sorbent was determined to follow the order Fe(III) > Cr(III) >> Cu(II) > Cd(II) > Pb(II) > Ni(II). Two standard reference materials were used for checking the accuracy and precision of the method. The proposed method was successfully applied to the analysis of environmental samples. This ligand material has great advantage for adsorption of transition-metal ions from aqueous medium due to its high degree of organofunctionalization associated with the large adsorption capacity, reutilization possibility, and rapidity in reaching the equilibrium.

“…A comparison of the proposed system with other preconcentration procedures using several sorbents is given in Table 5. The concentration factors (CF) and the relative standard deviations obtained for the studied elements are comparable to those presented by other methods described in the literature [5,6,[32][33][34][35][36][37][38]. The detection limits are similar or lower than those obtained with other sorbents [5,7,32,[34][35][36][37][38].…”

“…In combination of SPE-FAAS, the expected interference generally may be attributed to the anions or cations which respectively complex metal ions or bind to this new sorbent [35][36][37]. The possible interference of other metal ions and a few anions on the recovery of Cu 2+ , Pb 2+ , and Fe 3+ ions was investigated, and the results are summarized in Table 2.…”

In this study, a solid-phase extraction method combined with atomic absorption spectrometry for extraction, preconcentration, and determination of iron (Fe(3+)), copper (Cu(2+)), and lead (Pb(2+)) ions at trace levels in water samples has been reported. The influences of effective parameters such as flow rate, pH, eluent conditions (type, volume, and concentration), sample volumes, and interference of matrix ions on metal ions recoveries were studied. Under optimized conditions, the limits of detection were found in the range of 0.7-2.2 μg L(-1), while preconcentration factors for Fe(3+), Cu(2+), and Pb(2+) ions were found to be 166, 200, and 250, respectively, and loading half time (t (1/2)) values were less than 2 min for all analyte ions. The proposed procedure was applied for the determination of metal ions in different water samples with recovery of >94.4% and relative standard deviation less than 4.4% for N = 5.
