Cu at trace concentrations acts as both a micronutrient and a toxicant in marine and fresh water systems [1][2][3][4][5][6][7][8] .This element is needed by plants at only very low levels and is toxic at higher levels. At these levels, Cu can bind to the cell membrane and hinder the transport process through the cell wall. Cu at nearly 40ng mL -1 is required for normal AbSTRACTA novel, simple method has been developed for the preconcentration of Cu(II) based on the adsorption of its Schiff's Naphtol-2-(Pyridylazo-2)-1 (PAN) complex on a Single walled carbon nanotubes (SWCNTs) onto C 18 cartridge . The influence of acidity, eluting agents, stability of the cartridge, sample volume and interfering ions has been investigated in detail. The adsorbed complex could be eluted using HNO 3 4M and the concentration of Cu(II) was determined by flame atomic adsorption spectrometry (FAAS). A detection limit of 0.10 µgL -1 could be achieved and the developed procedure was successfully applied for the determination of Cu(II) in spiked water samples . The preconcentration factor attainable for quantitative recovery (>97%) of Cu(II) was 125 for a 1000mL sample volume. The mentioned method was successfully applied on the determination of Cu(II) in different water samples. In this method, relative standard deviation (RSD) is %1.25.

“…Some analogous compounds of BDAP such as 2-(6-methyl-2-benzothiazolylazo)-5-diethylaminophenol (MBTAE) [22][23][24] and 2-(2-thiazolylazo)-5-diethylaminophenol (TADAP) [25][26][27] have been applied as a precolumn derivatizing reagent in high-performance liquid chromatography (HPLC). Another analogue, 2-(6-bromo-2-benzothiazolylazo)-5-diethylaminophenol, was synthesized and applied to the spectrophotometric determination of nickel [28] and zirconium [29]. According our knowledge, the use of BDAP in analytical procedures has not been reported before.…”

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.
