Adsorption of Heavy Metal Ions from Multi-Ion Solutions Using Polysaccharide Hydrogels

Polysaccharides
Adsorption has been found to be highly effective for removing heavy metals from polluted industrial wastewater. Adsorbents of biological origin, such as negatively charged polysaccharides, e.g., alginate and carrageenan, have attracted a lot of attention

Microfabricated heavy metal ion sensor

Sensors and Actuators B: Chemical, 1995
Abstract A novel microfabricated electrochemical sensor has been developed for the detection and measurement of heavy metal ions in aqueous media. The sensor consists of a silicon substrate, on which is fabricated an electrically interconnected, but diffusionally isolated, array of thin-film iridium microelectrodes upon which a thin film of mercury ...

The cell wall functions in plant heavy metal response

Ecotoxicology and Environmental Safety
Nonessential metals (e.g., cadmium (II), etc) and essential heavy metals (e.g., copper (II), etc) are both toxic for plants at high concentrations. The plant cell wall, which consists of pectin, cellulose, hemicellulose, lignin and proteins, acts as the ...
