The Adsorption of Heavy Metal Ions

Advances in Science and Technology
The aim of the study is to research of the adsorption properties of heavy metal ions Pb2+, Cd2+ and Ni2+ from industrial wastewater. For the adsorption of heavy metal ions, natural clinoptilolite was used, which belongs to the Ai-Dag deposit of the Tovuz-Kazakh region of Azerbaijan.

Mechanisms of cell activation by heavy metal ions

Journal of Biomedical Materials Research, 1998
Heavy metal ions can be released by corroding metallic implants into the surrounding tissue. When they enter blood vessels some of them are carried by proteins like albumin and can be taken up by endothelial cells lining the vessels. To study their involvement in the inflammatory response we investigated heavy metal ion induced effects in cultured ...

Ion Exchange Extraction of Heavy Metal Ions from Wastewater

Separation Science and Technology, 2005
Abstract In this study, ion‐exchange resins of the cation exchanger universal (KU)‐2 type with functional sulfate groups, a carboxyl‐containing cation exchanger of a carboxyl containing cationite (KB) type, and polyampholyte amphoteric carboxyl containing ion exchanger (ANKB)‐35 were studied for Ni2+ and Cu2+ ion extraction from water solutions.

Selective Optode Membranes for Heavy Metal Ion Detection.

1998
Optode membranes for Lead(II) based on an ion-exchange mechanism and neutral ionophores show that the calix[4]arene ionophores developed for CHEMFETS can be used in optical sensing schemes. To achieve pH independent sensor response, chromoionophores have been developed based on these neutral ionophores, which show a optical response to the complexation

Specific heavy metal ion recovery with ion‐imprinted cryogels

Journal of Applied Polymer Science, 2015
ABSTRACTIn this study, the functional monomers, N‐methacryloyl‐l‐aspartic acid and N‐methacryloyl‐l‐cysteine were synthesized through a reaction between appropriate amino acids and methacryloyl chloride. Then, Pb(II) or Cd(II) ion‐imprinted 2‐hydroxyethyl methacrylate based cryogels were prepared by free radical polymerization method under partially ...

The effective ion-ion interaction of heavy alkali metals

Solid State Communications, 1982
Abstract The effective ion-ion interaction for the heavy alkali metals is calculated by a full non-local model potential, including exchange and correlation in the screening according to Vashishta and Singwi and in the RPA. The inclusion of the s - d hybridization effects merely following Harrison's theory for transition metals turns out to be ...

Trace analysis of heavy metal ions by ion chromatography

Chromatographia, 1989
An ion chromatographic separation technique for heavy metal ions is described. Using pressure-stable, silica-based, ion-exchange supports and standard HPLC equipment with post-column reaction detector high resolution is achieved as well as extremely high sensitivity in the parts per trillion (ppt)-range.

Adsorption of heavy metal ions by immobilized phytic acid

Applied Biochemistry and Biotechnology, 1997
Phytic acid (myoinositol hexaphosphate) or its calcium salt, phytate, is an important plant constituent. It accounts for up to 85% of total phosphorus in cereals and legumes. Phytic acid has 12 replaceable protons in the phytic molecule, rendering it the ability to complex with multivalent cations and positively charged proteins. Poly 4-vinyl pyridine (

Heavy metal fluoride glasses: modifications induced by ion implantation

Journal of Non-Crystalline Solids, 1989
Abstract Samples of fluorozircnate (ZBLAN) glasses were subjected to Argon irradiation at energies of 50 and 100 keV and a fluence of 5×1016 ions/cm2. The modifications induced by the implants were characterized by nuclear analysis (Rutherford backscattering), XPS, electron probe and optical techniques.
