“…/MNS 3 . Table 5 shows the adsorption capacity and the time required for achieving equilibrium condition for the removal of copper and lead ions by the studied adsorbents in the present work, and those found by using the adsorbents p-dimethylaminobenzaldehyde-modified nanometer SiO 2 , SiO 2 -DMABD, (Cui et al 2006), sodium dodecyl sulfate-coated poly(vinyl)chloride modified with bis(2-hydroxyacetophenone)-1,4-butanediimine, SDS-PVC-BHABDI, (Marahel et al 2009) and Schiff basemodified nanocomposite, Fe 3 O 4 /SiO 2 -Pr-N = salicylaldehyde, (Moradinasab and Behzad 2014). The comparison of the data presented in Table 5 shows, although the capacity of SiO 2 -DMABD and modified nanocomposite Fe 3 O 4 /SiO 2 toward copper ions is remarkably higher than the studied adsorbents, these adsorbents are more efficacious materials with respect to the modified SDS-PVC adsorbent.…”

Nanosilica particles modified by Schiff base ligands 3-methoxy salicylaldimine propyl triethoxysilane (MNS 1 ), 5-bromo salicylaldimine propyl triethoxysilane (MNS 2 ) and 3-hydroxy salicylaldimine propyl triethoxysilane (MNS 3 ) were prepared, and their potential for separation of copper, lead, zinc, cadmium, cobalt and nickel ions from aqueous solutions was examined. The effect of parameters influencing adsorption efficiency including aqueous-phase pH, amount of adsorbent, stirring time and initial concentration of the metal ions was assessed and discussed. Although MNS 1 and MNS 3 removed lead ions efficiently, all adsorbents showed strong selectivity toward copper ions. It was shown that, under some circumstances, MNS 3 decreased the amount of other ions, particularly cobalt, in the aqueous phase. The adsorbents were also applied for removal of copper and lead ions from real samples. Possible quantitative desorption of the metal ions loaded onto the adsorbents suggests their multiple uses in adsorption-desorption process. Investigation of temperature dependency of the process led to determination of the DH°, DS°and DG°values. This investigation indicates that the adsorption of copper ions onto the all studied adsorbents and lead ions onto MNS 1 and MNS 3 is endothermic. The Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms were tested to describe the equilibrium data. Pseudo-first-order, pseudo-secondorder, Elovich and intra-particle diffusion equations were applied to study the kinetics of copper and lead adsorption onto the modified nanoparticles. This investigation indicates that the process for all adsorbents follows pseudosecond-order kinetics and suggests a chemisorption mechanism for the adsorption processes by the studied adsorbents.

“…In this context, accurate selection of appropriate support and chelating agents are critical for obtaining full recoveries of the ions with high enrichment factors [17][18][19][20][21][22][23][24][25][26]. Nowadays, nanometer agents have received great attention due to their high enrichment capacities [27][28][29][30][31][32][33][34]. Moreover, nanoparticle-based sorbents exhibit intrinsic surface reactivity and high surface areas so that their surface could be strongly modified by various chelating agents.…”

In this study, a new sorbent based on the gold nanoparticle loaded in activated carbon (Au-NP-AC) was synthesized and modified by bis(4-methoxy salicylaldehyde)-1,2-phenylenediamine (BMSAPD). This sorbent, which is abbreviated as Au-NP-AC-BMSAPD, has been applied for the enrichment and preconcentration of trace amounts of Co(2+), Cu(2+), Ni(2+), Fe(2+), Pb(2+), and Zn(2+) ions in real samples. All metal ions under study were retained on the Au-NP-AC-BMSAPD sorbent by complexation of the ions with the BMSAPD ligand, providing an efficient preconcentration fashion. The retained metal ions were then eluted from the sorbent by HNO(3) and detected by flame atomic absorption spectrometry. The analytical parameters including pH, amount of ligand, and the nature of the eluent and solid phase were evaluated to obtain the optimum condition for the preconcentration factor. Following the optimum conditions, a preconcentration factor of 200 was obtained for all the metal ions under study with detection limits of 1.4-2.6 ng mL(-1). The method has been successfully applied for the extraction and determination of the ion content in the same real samples with recoveries in the range of 95-99.6% and a relative standard deviation lower than 4.0%.

“…The theoretical preconcentration factor, calculated as the ratio of the initial sample volume (1000 mL) to the final volume after preconcentration (10.0 mL), was 100. According to the figures of merit of the proposed method in comparison with other reported solid phase extraction methods, 26,[37][38][39] the proposed method showed very good sensitivity and precision for determining Cu 2+ and Pb 2+ ions. The results are summarized in Table 1.…”

Recebido em 21/3/13; aceito em 16/5/13; publicado na web em 25/7/13 A simple and fast approach for solid phase extraction is herein described, and used to determine trace amounts of Pb 2+ and Cu 2+ metal ions. The solid phase support is sodium dodecyl sulfate (SDS)-coated γ-alumina modified with bis(2-hydroxy acetophenone)-1,6-hexanediimine (BHAH) ligand. The adsorbed ions were stripped from the solid phase by 6 mL of 4 M nitric acid as eluent. The eluting solution was analyzed by flame atomic absorption spectrometry (FAAS). The sorption recovery of metal ions was investigated with regard to the effects of pH, amount of ligand, γ-alumina and surfactant and the amount and type of eluent. Complexation of BHAH with Pb 2+ or Cu 2+ ions was examined via spectrophotometry using the HypSpec program. The detection limit for Cu 2+ was 7.9 µg L -1 with a relative standard deviation of 1.67%, while that for Pb 2+ was 6.4 µg L -1 with a relative standard deviation of 1.64%. A preconcentration factor of 100 was achieved for these ions. The method was successfully applied to determine analyte concentrations in samples of liver, parsley, cabbage, and water.
