چکیده
Attachment of EDTA-like chelators to carbon coated metal nanomagnets results in a magnetic reagent for the rapid removal of heavy metals from solutions or contaminated water by three orders of magnitude to concentrations as low as microg L(-1).

Heavy metals removal from wastewater by using different kinds of magnetite nanoadsorbents: effects of different organic and inorganic coatings on the removal of copper and lead ions
Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of t...

Anzali International wetland is one of the most valuable water resources as registered in Ramsar convention with an extent of about 150 km2 in the south Caspian Sea. This wetland, not only has ecological and biological importance for migratory birds and rare fish species, but also is used for farms to discharge into the Caspian Sea through this wetland. Therefore its pollution control is very ...
متن کاملPotentiality of agricultural adsorbent for the sequestering of metal ions from wastewater
The expensive nature of metal ions detoxification from wastewater have restricted the use of conventional treatment technologies. Cheap, alternative measures have been adopted to eliminate metal contamination, and adsorptions using agricultural adsorbents seem to be the way forward. The use of agricultural adsorbents for cadmium (II), copper (II) and lead (II) ion removal has gained more intere...
