“…Thermodynamic studies have shown that the adsorption process is spontaneous and endothermic. This approach is superior to earlier reported chromium separation/preconcentration methods 12,[34][35][36][37][38] in terms of the detection limit and precision. This system can be used for chromium speciation analysis in wastewater samples.…”

N(2-Thiophenyl)-1-(2-hydoxyphenyl)Imine (NTPHPI) was used as a proper complexing agent for the preconcentration by cloud point extraction followed by atomic absorption spectrometric to determine of Ni 2+ , Cu 2+ and Co 2+ ions in real samples. NTPHPI and Triton X-114 were used as hydrophobic ligand and non-ionic surfactant respectively and the pH of 8 was chosen as optimum. Under the optimized experimental conditions, the selective preconcentration and determination of low concentration of Ni 2+ , Cu 2+ and Co 2+ ions as 1, 5 and 6 ng mL -1 can be made respectively. The proposed method was successfully applied to the preconcentration and low-level determination of the cited ions in different water, chocolate and honey samples.

“…Recently, the solid phase extraction method has emerged as a powerful tool for enrichment/separation of metal ions because of its various advantages over other methods, such as higher preconcentration factor, lesser waste generation, lower matrix effect, use of less toxic solvents, saving of time and cost, easiness of regenerability of a solid phase, and thereby more reusability. Other advantages of the SPE method are relatively high concentration factor and the ability of treating large-volume samples compared to other separation and preconcentration techniques (Divrikli et al 2007). The solid phase extraction of metal ions present at micro/trace level in environmental samples, high-purity materials, biological samples, and other complex matrices makes possible their determination with cheap and commonly available analytical techniques, such as FAAS.…”

A new chelating resin, Amberlite XAD-4 loaded with N,N-bis(salicylidene)cyclohexanediamine (SCHD), was synthesized and characterized. The resin Amberlite XAD-4-SCHD was used for selective separation, preconcentration, and determination of Cu(II), Pb(II), and Ni(II) ions in water samples by flame atomic absorption spectrometry (FAAS). Effects of pH, concentration, and volume of elution solution; flow rate of elution; and sample solution, sample volume, and interfering ions for the recovery of the analytes were investigated. These metal ions can be desorbed with 0.5-M HNO3 (recovery, 98%-101%). The sorption capacity was found between 1.38×10(-1) and 3.58×10(-1) mmol/g. In order to evaluate the accuracy of the proposed procedure, the certified reference materials, BCR-032 (Moroccan phosphate rock) and BCR-715 (industrial effluent wastewater), were analyzed. The detection limits of the method were found to be 0.11, 1.91, and 0.43 μg/L for Cu(II), Pb(II), and Ni(II), respectively. The method was applied to the extraction and the recovery of copper, lead, and nickel in wastewater and other water samples.
