“…Copper at trace concentrations acts as both a micronutrient and a toxicant in marine and fresh water systems [1][2][3][4][5][6] . This element is needed by plants at only very low levels and is toxic at higher levels.…”

In this method to amounting of the trace amount of Cu (II) ions in aqueos Samples by CNT modified Amino-pyrrolidine dthiocarbamate (APDC) which in order to improve the performance of extraction and preconcentration was used. Amounting of the ions density in solution was performed by the method of flame atomic absorption spectrometry. The effective parameters on extraction such as: effect of pH, the amount and eluent solvent, time of extraction and effect of other cation were optimized. Concentrate factor was found 57 and LOD method of limit of detection was found to 0. 6µg.L -1. the relative standard deviation is 0.76% (RSD%).

“…Preconcentration can solve the above two problems and lead to simplified heavy metal determination. There are many methods of preconcentration, including cloud point extraction, 12 22 inductively coupled plasma mass spectrometry, 23 liquid-liquid extraction, 24 electrothermal atomic absorption spectrophotometery 25 and solid phase extraction. [26][27][28] Among the various preconcentration methods, solid-phase extraction (SPE) is one of the most effective multi-element preconcentration methods because of its simplicity, rapidity and ability to attain a high concentration factor.…”

In this study, a simple, sensitive and accurate column preconcentration method was developed for the determination of Cd, Cu and Pb ions in river water, urine and sediment samples by flame atomic absorption spectrometry. The procedure is based on the retention of the analytes on a mixed cellulose ester membrane (MCEM) column from buffered sample solutions and then their elution from the column with nitric acid. Several parameters, such as pH of the sample solution, volume of the sample and eluent and flow rates of the sample were evaluated. The effects of diverse ions on the preconcentration were also investigated. The recoveries were >95 %. The developed method was applied to the determination of trace metal ions in river water, urine and sediment samples, with satisfactory results. The 3δ detection limits for Cu, Pb and Cd were found to be 2, 3 and 0.2 μg dm−3, respectively. The presented procedure was successfully applied for determination of the copper, lead and cadmium contents in real samples, i.e., river water and biological samples

“…However, in cases of iron overload the natural storage and transport proteins are overwhelmed and the iron spills over into other tissues and organs, such as the muscle, spleen and liver [1], proving to be toxic [2]. Numerous techniques, such as spectrophotometric [3][4][5][6], potentiometric titration [7], flame [8] and electrothermal atomic absorption spectrophotometry [9], flow-injection [10-*Corresponding author. E-mail: gkhayatian@yahoo.com 14] and photoacoustic [15] methods, have been used for the determination of iron species.…”

A simple and selective method for rapid extraction and determination of trace amounts of iron(III) using octadecyl-bonded silica membrane disks modified with 2-mercaptopyridine-1-oxide and flame atomic absorption spectroscopy is presented. The factors influencing extraction efficiency were evaluated, including the nature of the counter anion, pH of the sample solution, amount of ligand, flow rate of the sample and type of stripping solution. The maximum capacity of the membrane disk, modified by 10 mg of the ligand, was found to be 926 ± 6 g of iron(III). The breakthrough volume was greater than 2500 ml. Iron(III) was completely recovered ( 99%) from water with a preconcentration factor of more than 166. The limit of detection of the proposed method was 0.63 ng ml -1 . The various cationic interferences had no effect on the recovery of iron(III) from the binary mixtures. The proposed method was applied to the determination of iron(III) from three different water samples.
