Heavy metals are a threat to human health and ecosystem. These days, great deal of attention is being given to green technologies for purification of water contaminated with heavy metal ions. Biosorption is one among such emerging technologies, which utilizes naturally occurring waste materials to sequester heavy metals from wastewater. Cadmium has hazardous impact on living beings; therefore, ...

Adsorption of lead(II) as a major heavy metal pollutant onto nano-adsorbents of Andalusite, Kyanite and Sillimanite was studied in a batch system. Nano­-adsorbents were prepared via crushing, using a planetary ball mill and then characterized by different analyses such as: SEM, XRD, XRF and FT-IR. Major factors affecting the adsorption process were studied including pH, adsorbents dosage, initi...

Background and aims: The removing of (potential) toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. The aim of present study was to investigate the various methods for lead removal of lead ions from industrial wastewater. Methods: This study was a review research. Data were collected through different databases in va...

To study the extent of removal of Cu(II) ions from the electroplating industrial effluent, metal resistant fungal strain of Penicillium janthinellum was selected for the present study. Response surface methodology was used to optimize the sorption process variables i.e. temperature (20-40 oC), biomass concentration (0.5-2.5 mg/l), pH (2.0-6.0) and initial concentration of metal ions (20-100 mg/...

Magnetic nanoparticles are used in adsorptive removal of heavy metals from polluted wastewater. However, their poor stability in an acidic medium necessitates their protection with a coating layer. Coating magnetic nanoparticles with carbon showed proper protection but the heavy metal removal efficiency was slightly weak. However, to boost the removal efficiencies of surface functionalization, ...

background & aims of the study: heavy metals contaminate drinking water, air and soils. it is very harmful for humans and other live organisms. phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. this method is accepted environmentally, economically and aesthetically. the purpose of this study was to assess tamarix hispida capacit...

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).

Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...
