Electrochemical detection of heavy metal ions in water

Chemical Communications, 2021
Electrochemical sensors demonstrate outstanding performance at detecting heavy metal ions, with a high specific surface area and high sensitivity which can excellently complete the on-site detection of trace heavy metal ions in water.

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, 2016
A 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.

Heavy Metal Ion Clusters

Nature Physical Science, 1971
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, 1990
Chemical 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, 2003
An 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.

Removal of Heavy Metal Ions

1997
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,
