    Abstract: The word “nano” means; one in a billion of a physical mass. Nanotechnology has been frequently beneficial branch of science in recent years by applying nanoparticules to various fields. Synthesis of particules in nano is size, has increased the covered surface area in unit volume and this made expanding of using nanoparticules in many different areas. Especially the metal nanoparticules have many advantages leading to development of many ways of synthesis. One of these methods of synthesis is “chemical reduction”. This work makes a research on the anion effects on the size mass nanoparticules of metals Cu(II), Ni(II), Co(II), Zn(II) and Mn(II) after reduction to nano size of sodium bor hidrur which belongs to salt of asetat and chlor, nitrate, sulfate. Depending on the radius ratios and solubility values of metal cations and anions, the nanoparticle obtained from Cu(CH3COO)2 salt has the smallest radius. Nanometal particles with the largest radius were obtained by reduction of Cl- ion salts. Size analyze and passing electrone microscope (SEM) analysis made about the characterization of synthesised nano particules.

    Abstract: Hazelnut shell biosorbent immobilized on Amberlite XAD-4 polymer resin as solid phase extraction method was developed and used for preconcentration of Cu(II) and Cd(II) ions from aqueous solutions. Concentrations of analytes in solutions were determined by Flame Atomic Absorption Spectrometry after extraction with column technique. Functional groups of nutshell biosorbent immobilized on resin were characterized by Fourier transform infrared spectrometry. Optimized critical parameters for preconcentration of Cu2+ and Cd2+ ions from sample solutions with nutshell immobilized on the resin were the pH value of solution, type of eluent solutions, the flow rate of sample solution, quantities of nutshell biosorbent, Amberlite XAD-4 resin, and enrichment factors, respectively. Detection limits of Cu2+ and Cd2+ ions found were 0.29 µg L-1 and 0.25 µg L-1, respectively. The method proposed was applied for determinations of Cu2+ and Cd2+ ions in standard reference material (BCR-670 aquatic plant sample) for accuracy and applied to real water samples such as wastewater and Van lake water. At the 95% confidence level, relative standard deviations (RSDs) were found as 1.44% for Cd2+ and 1.21% for Cu2+ ions with three replicate measurements.
