“…SPE has been reported as one of the most powerful techniques because it minimizes solvent usage and exposure, disposal costs, and extraction time for sample preparation. Several adsorbents have appeared because of the popularity of SPE for the selective extraction of analytes, such as alumina, C18, molecular imprinted polymers, cellulose, silica gel, activated carbon, and carbon nanotubes …”

A new series of polyarylidene(keto amine)s (PAKAs) 3 a 23 e based on thiophene moieties in polymer main chains were synthesized with the solution polycondensation technique. The polymers were synthesized by the reaction of the new monomer 1,1 0 -(1E,1 0 E)-(2-oxocyclohexane-1,3-diylidene)bis(methanylylidene)bis(thiophene-5,2-diyl)bis(2-chloroethanone) (2) with different diamines. The new monomer was first synthesized under the normal conditions of the Friedel-Crafts reaction. The results obtained from both elemental and spectral analyses were consistent with the chemical structure of the new monomers and the polymers. Moreover, the identification of the polymers was carried out with different characterization techniques. The analytical competition of the newly synthesized PAKA polymers as selected examples (3 d and 3 e ) was also evaluated for a selective extraction of metal ions, including Cd(II), Co(II), Cu(II), Cr(III), Fe(III), Ni(II), and Zn(II), before their determination by inductively coupled plasma-optical emission spectrometry. The results of the selectivity study demonstrated that the 3 d and 3 e polymers was the most selective toward Co(II) and Fe(III), respectively. However, the adsorption capacity of 3 d for Co(II) was improved by 10.10% in comparison to that of 3 e for Fe(III) after only 1 h of contact time. Moreover, the adsorption isotherm data also showed that the adsorption process was mainly monolayer on the homogeneous adsorbent surfaces of both polymers.

“…The classical fire assay and the precipitate are generally tedious and time-consuming. Numerous materials, including ion exchange resin (IER) (Hidalgo et al, 2006), functionalized activated carbon (AC) (Zhang et al, 2011), cellulose fiber (CF) (Dwivedi et al, 2014) have been obtained. However, small size of AC cause high pressure in the SPE cartridge.…”

“…Activated carbon has been used for the adsorption of many metal ions (Channarong et al 2010;Moreno-Pirajan and Giraldo 2012), ionic surfactant (Gupta et al 2003;González-García et al 2004), and so forth. EXTRACTION OF Cd BY MODIFIED ACTIVATED CARBON 1979 In order to improve the adsorption capacity and selectivity of AC, Some chelating agents have been modified on AC as solid adsorbents for the preconcentration of some metal ions such as 1-amino-2-naphthol-4-sulfonate (Zhang et al 2011), sodium diethyldithiocarbamate (Tavakkoli, Habibollahi, and Tehrani 2012), cadmium selenide nanoparticle (Ghaedi et al 2011), tetrabutylammonium hydroxide (Tsoi and Leung 2011), bis(2-hydroxyacetophenone)ethylendiimine (Ghaedi et al 2009), ammonium pyrrolidinedithiocarbamate (Jiang et al 2008), xylenol orange (Ensafi and Shiraz 2008), and so forth.…”

A novel absorbent was prepared by sodium dodecyl sulfonate (SDS)-modified activated carbon (SDS-AC) and was employed as the microcolumn packing material for separation/preconcentration of trace Cd(II). The method based on Cd(II) was quantitatively retained by SDS-AC sorbent, which entailed cation exchange nature and negative charged surface, facilitating favorable retention of positively charged ions. The retained Cd(II) was effectively recovered with elution by 1 mol Á L À1 HNO 3 , and the eluent was quantified by electrothermal atomic absorption spectrometry (ET-AAS). Under the optimized conditions, the limit of detection (LOD) for Cd(II) was 3 ng Á L À1 with the consumption of 20.0 mL sample solution. The relative standard deviation (RSD) for ten replicate measurements of 50 ng Á L À1 Cd(II) was 2.9%. The developed technique was demonstrated for the determination of trace Cd(II) in water samples and the recoveries for spiked samples were found to be in the range of 94.9-107.2%. For validation, two certified reference materials of water samples (GBW08607 and GBW08608) were analyzed, and the results obtained were in good agreement with the certified values.
