Antibody-based sensors for heavy metal ions

Biosensors and Bioelectronics, 2001
Competitive immunoassays for Cd(II), Co(II), Pb(II) and U(VI) were developed using identical reagents in two different assay formats, a competitive microwell format and an immunosensor format with the KinExA 3000. Four different monoclonal antibodies specific for complexes of EDTA-Cd(II), DTPA-Co(II), 2,9-dicarboxyl-1,10-phenanthroline-U(VI), or ...

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 ...

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.

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 contamination in ion implantation

AIP Conference Proceedings, 1997
Reduction of metallic contamination during ion implantation is becoming increasingly critical for device performance. Modern implanters are being developed with novel beamline coating materials and optics to keep sputtered contamination to a minimum. However chemical processes occur in the implanter which lead to contaminants being deposited onto the ...

Metal Oxide Composites for Heavy Metal Ions Removal

2021
Contamination of heavy metals is a major concern nowadays due to various environmental problems and hazardous effects on human, living organisms and eco-system. It is therefore of paramount importance to devise strategies for heavy metal ions removal which are workable and economical before discharging the wastewater such as industrial wastewater into ...

Removal of heavy metal ions by nanofiltration

Desalination, 2013
Abstract This study describes the rejection of heavy metal ions using a commercial nanofiltration membrane (NF270). The effect of feed pH, pressure and metal concentration on the metal rejections and permeate flux and in some cases permeate pH was explored.

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.
