Extraction and preconcentration of Pb(II) from water and soil samples using modified activated carbon
In this work, a new extractant was prepared by immobilizing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, (5-Br-PADAP), on the activated carbon and applied to extraction of Pb(II) prior to determination by flame atomic absorption spectrometry. It was confirmed by FT- IR analysis. The metal ion was retained on the 0.05 g of the sorbent in the pH range 6-8, and then eluted with 5 mL of 0....
متن کاملPreconcentration and Determination of Chromium (III) from Sea Water Samples Using Ion Imprinted Activated Carbon
A simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. The resulting sorbent has been characterized using Fourier transform infrared spectroscopy (FT-IR), elemental analysis, thermogravimetric analysis (TGA) and evaluated for the preconcentration and de...

متن کاملSolid phase selective and extractive preconcentration of silver ion from aqueous samples on modified silica gel with 5-(4-dimethylaminobenzylidene)-rhodanine; prepared by sol-gel method.
A new modified silica gel doped with 5-(4-dimethylaminobenzylidene)-rhodanine was prepared for separation, preconcentration and determination of silver ion by atomic absorption spectrometry. This new modified silica gel was used as an effective adsorbent for the solid phase extraction of Ag(+) from aqueous solutions. The variables that influence the adsorption/desorption of trace levels of Ag(+...
متن کاملDetermination of ultra trace amount Chromium in water samples with the 1-(2-PyridylAzo)-2-Naphthol, (PAN) by the bromate ion in sulfuric acid with kinetic spectrophotometric method
A new kinetic spectrophotometic method for the determination of trace amount Chromium (III) in Teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –PyridylAzo ) - 2 - Naphthol, (PAN), by potassium bromated in sulfuric acid. The reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. Under the optimumcondi...
