Metal Oxides for Removal of Heavy Metal Ions
2021“Heavy metals” are elements of high atomic weight with a density much higher than that of water. Presence and the use of these heavy metals are found in agriculture, medicine, electronics, paints, and many others. These heavy metals are non-biodegradable and are toxic to human and animal health if found above the permissible limit.

Ion Mobility Spectrometry of Heavy Metals
Analytical Chemistry, 2016A simple, fast, and inexpensive method was developed for detecting heavy metals via the ion mobility spectrometry (IMS) in the negative mode. In this method, Cl(-) ion produced by the thermal ionization of NaCl is employed as the dopant or the ionizing reagent to ionize heavy metals.

DURING the past several years increasing attention has been devoted to studies of the properties of gaseous metal ions. This is a result of an interest in their behaviour in the atmosphere1, as well as the realization that the information obtained for the gaseous metal ion complexes provides a bridge between solution and gas phase chemistry2.

An Optical Sensor for the Detection of Heavy-Metal-Ions
Sensors and Actuators B: Chemical, 1990Chemical sensors with improved specifications could play an important role in environmental analysis. Highly selective and sensitive sensors for the determination of trace metals would have a great potential of application in environmental in-line-monitoring and -control.

Competitive Sorption of Heavy Metal Ions by Soils
Environmental Engineering Science, 2003An experimental study is presented on heavy metal pollution of soils. In particular, Pb2+, Zn2+, Cd2+ are considered as most representing the pollution of a Sardinian (Italy) area, where important mining activities connected to the extraction of blende and galena have been carried out in the past.

The production of wastes containing, among others, heavy metals, has become today an immense problem, as clearly shown (for example) in Table 1; these wastes are around one third of the total non-municipal, mainly industrial, solid wastes produced annually in Greece. In areas like the Mediterranean countries, where considerable water reuse is necessary,

Antibody-based sensors for heavy metal ions
Biosensors and Bioelectronics, 2001Competitive 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, 1998Heavy 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 TechnologyThe 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, 1997Phytic 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 (
