“…Finally, 10 µl portion of the eluate was injected into HPLC for analysis. Furthermore, enrichment factor can be calculated which is the ratio of highest sample volume over lowest sample volume [ 33 – 35 ]. In the current study, the highest volume and the lowest sample volume were 200 ml and 0.7 ml, respectively.…”

A magnetic solid-phase extraction (MSPE) procedure on the newly synthesized magnetic β-cyclodextrin functionalized with toluene diisocyanate (TDI) as a linker and further modified with bio-polymeric spores of sporopollenin (MSp-TDI-βCD), was developed for the extraction of nonsteroidal anti-inflammatory drugs (NSAIDs), namely, indoprofen (INP), ketoprofen (KTP), ibuprofen (IBP) and fenoprofen (FNP) from water samples prior to their HPLC-DAD determination. The newly synthesized MSp-TDI-βCD was comprehensibly characterized using FT-IR, XRD, SEM-EDX, BET and VSM analyses. The separation of selected NSAIDs on MSp-TDI-βCD from aqueous solution was simply achieved by applying an external magnetic field via a permanent magnet. The MSPE parameters affecting extraction performance, i.e. sorbent dosage, sample volume, extraction and desorption time, type of organic eluent and volume and solution pH were investigated and optimized. The proposed method showed linear range between 0.5 and 500 ng ml−1, low limit of detection at S/N = 3 (0.16–0.37 ng ml−1) and limit of quantification at S/N = 10 (0.53–1.22 ng ml−1). The inter-day (n = 15) and intra-day (n = 5) precision for the proposed methods given by relative standard deviation (RSD%) was in the range of 2.5–4.0 and 2.1–5.5, respectively. The extraction recoveries of NSAIDs from environmental samples (tap, drinking and river water) ranged from 92.5% to 123.6%, with satisfactory precision (RSD% less than 12.4%).

“…In order to improve detection limits for elemental analysis, preconcentration procedures are frequently necessary (Bahar and Babamiri 2015) that have included solid phase extraction (Baysal, Kahraman, and Akman 2009;Turker 2007;Dasbasi et al 2015), dispersive solid-liquid extraction (Méndez et al 2015), carrier element-free coprecipitation (Duran et al 2015), cloud point extraction (Garcia et al 2015), and dispersive liquid-liquid microextraction (Bahar and Babamiri 2015;Li et al 2015). Most extraction methods are lengthy, require large volumes of organic solvents, and provide limited sensitivity and selectivity (Khan et al 2014).…”

In this study, oleic acid was The preconcentration of metals has been achieved with an external magnetic field overcoming the need for centrifugation (Duran et al 2015); filtration (Bahadir et al 2015), manual collection of extractant (Pourjavid et al 2015), or other specialized apparatus. The synthetic conditions for the modification were relatively mild and low cost compared to some methods in the literature (Ghazaghi et al 2015;Fouladian and Behbahani 2015).…”

Magnetic solid-phase extraction was used for the preconcentration of cadmium, lead, and cobalt in Moringa Oleifera with determination by flame atomic absorption spectrometry. Fe3O4 nanoparticles were modified by oleic acid to form the sorbent for magnetic solid-phase extraction. The modified sorbent was characterized by transmission electron microscopy, infrared spectroscopy, and X-ray diffraction. The preconcentration was optimized for the mass of nanoparticles, pH, adsorption time, the presence of coexisting ions, solution volume, eluent, and reuse. The optimized limits of detection were 0.09, 0.26, and 0.54 μg/L for Cd(II), Pb(II), and Co(II) with relative standard deviations below 4.3%. The method was employed for the analysis of Moringa oleifera and recoveries between 90.0 and 102.0% were obtained.

“…The separation and determination of silver ion at low concentrations and in the presence of other cations at high concentration requires selective techniques. The most usually used techniques for separation and preconcentration of trace amounts of silver are liquid-liquid extraction (Mohammadi et al 2009;Ahmed et al 1988), ion exchange resin (Dicinoski et al 2000), ion liquid micro extraction (Ashkenani and Taher 2012), cloud point extraction (Manzoori, et al 2007;da Silva et al 1998;da Silva, et al 2000), solid phase extraction (SPE) (Hajiagha-Babaei et al 2001;Yang et al 2009;Pu and Sun 1998;Safavi, et al 2004) And copericipitation (Pei and Fang 1994;Bloom and Crecelius 1984). Among these methods, Coprecipitation methods are mainly suggested for preconcentration of trace metal ions from various samples (Mendil et al indium, and samarium have been used (Soylak and Balgunes 2008;Doner and Ege 2005;Divrikli, Elci 2002;Saracoglu et al 2003).…”

In this work, silver iodide (Ag(I)) ions were separated via carrier element-free coprecipitation (CEFC) method by using an organic coprecipitating agent, 1,6-diamino-4-(4-chlornphenyl)-2-oxo-1,2-dihydropyridine-3,5-dicarbonitrile [DCODD] prior to its determination by flame atomic absorption spectrometry (FAAS). Analytical parameters including pH of aqueous solution, amount of DCODD. Standing time, centrifugation rate and time, and sample volume were studied and optimized. Under the best experimental conditions, it was found that extraction can be performed from the sample volume of 500.0 for silver ion (preconcentration factor of 100.0). Linearity was maintained between 0.006-1.50 µg.mL −1 for silver. Detection limit for silver based on 3Sb was 1.60 ng.mL −1 . The relative standard deviation of eight replicate measurement of 0.20 Downloaded by [University of Cambridge] at 00:38 11 June 2016A c c e p t e d M a n u s c r i p t 2 µg.mL −1 of silver was 2.10%. Finally, the developed method was successfully applied to extraction and determination of the silver ions in the Lepidium draba L plant, water and standard samples and satisfactory results were obtained.
