Reusable Polyacrylonitrile?Sulfur Extractor of Heavy Metal Ions from Wastewater

Using Nanocomposites of Chitosan and Montmorillonite for Adsorption of Heavy Metal Ions from Wastewater

Common technologies for heavy metal removal are membrane separation, ion exchange, electro-deposition, and chemical precipitation. These methods prove to be costly and inept, especially in removing trace amounts of heavy metals [2]. Another disadvantage is the production of sludge or mud, which requires proper disposal and confi nement [3]. On the other hand, adsorption eff ectively removes con...

Potentiality 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...

Kinetic study of heavy metal ions removal from aqueous solutions using activated pumice stone

Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...

Applications of Magnetite Nanoparticles for Heavy Metal Removal from Wastewater

Thiol containing polymer encapsulated magnetic nanoparticles as reusable and efficiently separable adsorbent for heavy metal ions.

Fe3O4-PEDOT core-shell nanoparticles were fabricated by acid treatment mediated seeded polymerization and applied for highly efficient separation of heavy metal ions from contaminated waste water with an external magnetic field.
