ABSTRACT.A novel method using a packed column with perlite as a new sorbent has been developed for preconcentration of trace amounts of zinc and cadmium prior to their determination by flame atomic absorption spectrometry. Several factors that may be affected on the solid phase extraction (SPE) process, such as pH, sample volume, flow rate, volume and concentration of eluent were studied and optimized. Linearity was maintained between 0.001-0.1 µg mL −1 for zinc, and 0.001-0.3 µg mL −1 for cadmium. Detection limits based on 3Sb for zinc and cadmium were 1.8 and 1.6 ng mL −1 , respectively. The relative standard deviations of eight replicate measurements of 0.02 µg mL −1 of zinc and 0.05 µg mL −1 of cadmium ions were 2.1% and 1.8%, respectively. Finally, the developed method was successfully applied to extraction and determination of the zinc and cadmium ions in the water and food samples and satisfactory results were obtained.

“…The solutions were cooled, diluted, and filtered. The filtered solution was diluted to 100.0 mL with distilled water in a calibration flask (Malekpour et al 2009). Twenty-five milliliters of the pretreated sample solution was taken individually, and lead was determined by the proposed procedure.…”

The aim of the present work is the assessment of a new sorbent, prepared using silica gel coated with a pyrimidine derivative (allyl 6-methyl-4-phenyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate), for extraction and preconcentration trace amount of lead from different samples prior to determination by flame atomic absorption spectrometry. Common coexisting ions did not interfere with the separation and determination of lead at pH 6, so that lead ion completely adsorbed on the column. The limit of detection based on three times the standard deviation of the blank was found to be 0.53 ng mL(-1) in original solution. Obtained sorption capacity for 1 g sorbent was 5.0 mg Pb. The linearity was maintained in the concentration range of 0.1-30.0 ng mL(-1) for the concentrated solution. Eight replicate determinations of 2.0 μg mL(-1) of lead in the final solution gave relative standard deviation of ±2.6 %. The proposed method was successfully applied to the determination trace amounts of lead in the environmental samples such as carrot, rice, zardchoobe, and real water samples.

“…Several sorbents with different properties have been employed in SPE, including inorganic oxides, porous polymers, molecularly imprinted polymers, biosorbents or nanomaterials [8][9][10]. In addition, some publications have reported the use of zeolites for the preconcentration of inorganic [11][12][13] and organic [14,15] analytes. The original SPE has been modified several times to date, mainly related to miniaturization or automation [16].…”
