Summary This study presents a solid phase extraction (SPE) procedure for preconcentration and separation of Cu(II), Cd(II), Pb(II) and Ni(II), as their diethyldithiocarbamate chelates on Sepabeads SP‐207 resin using flame atomic absorption spectrometry. The parameters, including pH, sample volume, eluent type and volume etc., were optimised. The influences of the some alkali, alkali earth and transition metal ions on the involvement of copper(II), cadmium(II), lead(II) and nickel(II) were also examined. The preconcentration factor was calculated as 50. The limit of detections of the analyte ions (k = 3, N = 21) were 0.18 μg L−1 (Cu), 0.17 μg L−1 (Cd), 0.55 μg L−1 (Pb) and 1.67 μg L−1 (Ni). GBW 07605 Tea and NRCC‐DORM‐2 Dogfish Muscle certificated reference materials were used for confirm of method. The method was successfully performed for determination of Cu(II), Cd(II), Pb(II) and Ni(II) ions in water and food samples. The relative standard deviation was found to be lower than 7%.

“…Among the methods for treatment of wastewater, adsorption is the most favored one due to low cost (Miretzky and Cirelli 2010;Ozer et al 2012). Different materials such as activated carbon (Aci et al 2008;Imamoglu 2013), modified silica gels (Sivrikaya et al 2011;Ozcelik et al 2012), functional group bearing polymers (Altundag and Dundar 2009;Timur et al 2011), and organic-inorganic hybrid materials (Imamoglu and Gunes 2012; Imamoglu and Albayrak 2012) have been used as adsorbents for various metal ions or dyes.…”

The synthesis of 1,3,5-triazine-triethylenetetramine (TATETA), its characterization by infrared spectroscopy and elemental analysis, and its application for removal of Cr(VI) ions from aqueous solution is reported. The effects of pH, contact time, initial concentration of Cr(VI), sorbent dose, and temperature on adsorption were investigated and optimized by batch adsorption experiments. Adsorption was highest at acidic conditions with an equilibration time of 25 min. The adsorption followed a Langmuir model, with an adsorption capacity of 303 mg g À1 , was second order in its kinetics, and exothermic and thus spontaneous.

“…Adsorption outperforms the others in terms of effectiveness and cost, especially for the treatment of wastewater samples including metal ions at low concentration level than 100 ppm [7]. In the adsorption method, modified silica gels [8,9], functional group bearing polymers [10,11], inorganic-organic hybrid materials [12,13], and activated carbon (AC) [14,15] were used as an adsorbent. AC is widely preferred to the others due to its excellent properties such as large surface area and high adsorption capacity.…”

In this study, adsorption of Pb(II) and Mn(II) ions from aqueous solutions onto dehydrated hazelnut husks carbon (DHHC) was carried out batchwise in order to obtain optimal values for several effective parameters such as pH, contact time, dosage, and initial concentration. The adsorption of both Pb(II) and Mn(II) ions was found to be highly dependent on pH, which were optimum values of 4.5 and 5.5, respectively. The adsorption of both ions reached equilibrium conditions at 60 min. The experimental data of both ions were best fitted with the Langmuir model by maximum adsorption capacities of 133.3 and 44.8 mg g À1 for Pb(II) and Mn(II), respectively. Kinetic studies showed that Pb(II) and Mn(II) adsorption onto DHHC abided well by pseudo-second-order model.
