The effluent discharge containing chromium, which is toxic and potentially carcinogenic, will
lead to serious environmental problems. The removal of chromium is usually carried out by …

Solid metalliferous wastes (sludges, dusts, residues, slags, red mud and tailing wastes)
originating from ferrous and non-ferrous metallurgical industries are a serious environmental …

In the present study, activated carbon prepared from apple peels (ACAP) was used to
remove chromium (VI) from aqueous solution. The characterization of this ACAP has been …

Activated carbon was prepared from longan seed by chemical activation with sodium
hydroxide (NaOH). The longan seed activated carbon (LSAC) was characterized for surface …

In aqueous solutions, hexavalent chromium Cr (VI) was successfully removed by activated
carbon “Z. jujuba rubidium carbonate-activated carbon” obtained from waste lignocellulosic …

The difficulty in removal of heavy metals at concentrations below 10 mg/L has led to the
exploration of efficient adsorbents for removal of heavy metals. The adsorption capacity of …

Sustainable industrial development requires research on pollution control in industrial
wastewater, particularly sulfate-rich wastewater, which poses a threat to the environment …

Prepared activated carbon from fox nutshell by chemical activation with ZnCl 2 in the N 2
atmosphere was used for Cr (VI) removal from aqueous solution. Activated carbon was …

The aim of this study is to evaluate the impact of SRT (infinite, 60 and 30 days) on the
treatment and filtration characteristics of sequential anaerobic sulfate-reducing and aerobic …

Nano-zero-valent iron (nZVI) can efficiently control Cr (VI) pollution in groundwater, but its
application is hindered by the tendency of Fe 0 to agglomerate and form a passivation layer …
