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.

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 ...

Heavy Metal Ions Detection Using Nanomaterials-Based Aptasensors
Critical Reviews in Analytical Chemistry, 2022Heavy metals ions as metallic pollutants are a growing global issue due to their adverse effects on the aquatic ecosystem, and human health. Unfortunately, conventional detection methods such as atomic absorption spectrometry exhibit a relatively low limit of detection and hold numerous disadvantages, and therefore, the development of an efficient ...

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,

Heavy metal contamination in ion implantation
AIP Conference Proceedings, 1997Reduction 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 ...

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.
