“…Therefore, the EPA developed a clean sampling procedure of ambient water [14]. Solid phase extraction is a very sensitive, fast and economic preconcentration method [15], and various extractants are reported in the recent literature [15][16][17][18][19][20][21][22][23][24]. Alternatively, Ni can be preconcentrated using coprecipitation [25,26].…”

“…Various SPE materials which have been used for the preconcentration of trace metal ions as their chelates include, activated silica gel [40,41], carbon [42][43][44][45], polyurethane foam [46] microcrystalline naphthalene [47], C 18 cartridges [48], Chelex-100 [49], Alumina [50], functionalized polyurethane foam [51], modified silica [52,53], sulfur powder [54] and Amberlite XAD resins [55][56][57][58][59][60][61]. Amberlite XAD (styrene-divinyl benzene copolymer) resins, as the copolymer backbone for the immobilization of chelating ligands, have some physical superiority, such as porosity, uniform pore size distribution, high surface area, and chemical stability toward acids, bases, and oxidizing agents, as compared to other resins [62][63][64][65].…”

Synthetic resin, Amberlite XAD-4 was linked covalently with the third generation supramolecule, octa-O-methoxy resorcin [4] arene through -N=N-group to form chelating resin, which has been characterized and effectively used for the separation and preconcentration of metal ions such as Ni(II), Cu(II), Zn(II) and Cd(II). Critical parameters such as pH, flow rate, sorption capacity, breakthrough studies, distribution coefficient, preconcentration factor, concentration of eluting agents responsible for quantitative extraction of metal ions were optimized. The synthesized resin showed good binding affinity towards Ni(II), Cu(II), Zn(II) and Cd(II) under selective pH conditions. Good breakthrough capacity and fast exchange kinetics of the resin lead to effective separation of metal ions from their binary and ternary mixture by column method on the basis of pH and eluting agents. The resin could be reused for about 8 -10 cycles. The proposed method having the analytical data with the relative standard deviation (RSD) < 2% and with recoveries of analytes higher than 98%, reflects upon the reproducibility and reliability of the method which has been successfully applied in the separation and determination of Ni(II), Cu(II), Zn(II) and Cd(II) ions in synthetic, natural and ground water samples.

“…The adsorption equilibrium studies have revealed that pH is the dominant parameter controlling the adsorption [25]. Therefore, using activated carbon as collector permits the preconcentration and separation of low levels of analytes in several matrices [26][27][28][29].…”

ABSTRACT. Activated carbon modified method was used for the preconcentration and determination of copper content in real samples such as tap water, wastewater and a synthetic water sample by flame atomic absorption spectrometry. The copper(II) was adsorbed quantitatively on activated carbon due to its complexation with ethyl-2-quinolyl-β(p-carboxyphenyl hydrazone)dioxo propionate (EQCPDP). The adsorbed copper(II) ion on solid phase was eluted quantitatively by using nitric acid. The important parameters such as pH, amount of carrier, flow rate, amount of activated carbon and type and concentration of eluting agent for obtaining maximum recovery were optimized. The method at optimum conditions gives linear concentration range of 0.05-1.0 µg mL -1 of copper(II) with correlation coefficient of 0.9994 and the detection limit of 0.99 ng mL -1 . The preconcentration leads to enrichment factor of 175 and break through volume of 1750 mL. The method has good tolerance limit of interfering ions and selectivity and it has been successfully applied for determination of copper content in real sample such as blood, wastewater and river sample.
