A novel and selective method for the fast determination of trace amounts of Cu(II) ions in water samples has been developed. The procedure is based on the selective formation of Cu(II) at optimum pH by elution with organic eluents and determination by flame atomic absorption spectrometry. The method is based on complex formation on the surface of the ENVI-18 DISKTM disks modified Schiff base-ch...

In this study, a zinc plant purification cake (CINKUR Co. Turkey) was leached with sulphuric acid and an acidic leach solution containing Zn(II), Fe(II), Pb(II), Al(III), Cu(II), Co(II) and Ni(II) ions was obtained. After purification, ammonium thiocyanate and water were added to the remaining leach solution containing Co(II) and Ni(II) ions to adjust the chemical media and ion concentration. T...

The organic volatile constituents of biological fluids contain clinically useful diagnostic information for the recognition of metabolic disorders in man. To gain access to this information, it was necessary to develop the methodology for reproducibly stripping the trace concentrations of volatiles from biological fluids (dynamic headspace, gas phase-stripping, solvent extraction, and the trans...

Iron is the major impurity in pregnant leaching solutions (PLS) derived from heap and atmospheric acid of low-grade laterite ores. The PLS can be considered as a secondary resource for synthesis high added-value iron nanomaterials, provided that selectively separated polymetallic solution. In this study, feasibility selective separation was investigated by applying solvent extraction technique ...
