Ion Flotation of Copper(II) and Lead(II) from Environmental Water Samples

Synthesize of Ion Imprinted Polymer for Selective Extraction of lead (II) from Environmental Water Samples

A new Pb(II) imprinted mercapto functionalized Montmorillonite was synthesize by an easy one step reaction by combining a surface imprinting technique for selective phase extraction of Pb(II) prior to its determinations by flame atomic absorption spectroscopy. The modified sorbent was characterized by FTIR and studied for preconcentration and determination of Pb(II) in natural water samples. Th...

Preconcentration 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...

Separation of Tl(I) and Tl(III) from environmental water samples by flotation method coupled with Zeeman ETAAS determination.

An accurate, fast, and simple method for determination of thallium in environmental water samples with Zeeman electrothermal atomic absorption spectrometry (ZETAAS) by previous flotation preconcentration is given. The possibility of using cobalt(III) hexamethylenedithiocarbamate as a colloidal precipitate collector for simultaneous flotation separation of Tl(I) and Tl(III) from water matrices w...
