The presence of hexavalent chromium in wastewater is a potential hazard to aquatic
animals and humans. There are various mechanisms proposed, kinetic models used and …

Heavy metals present in industrial effluents enter the biological cycle through aquatic
organisms. Heavy metals undergo bioconcentration and prove to be toxic even in trace …

Functionalized Polyvinyl alcohol/sodium alginate (PVA/SA) beads were synthesized via
blending Polyvinyl alcohol (PVA) with sodium alginate (SA) and the glutaraldehyde was …

Industrial effluents contain multiple pollutants, which affect the quality of water remediation
operations. Hence, it is important to understand the outcome of the multicomponent …

Chromium exists in aqueous environment mainly in two forms namely hexavalent [Cr (VI)]
and trivalent [Cr (III)]. Cr (VI) is acutely toxic, mutagenic and carcinogenic whereas Cr (III) is …

Chromium is an insidious ecological pollutant that is of huge value for its toxicity. The
existing ecological objective to lower the heights of toxic materials in marine systems and to …

Activated carbon was prepared from Enteromorpha prolifera (EP) by zinc chloride activation.
The physico-chemical properties of EP-activated carbon (EPAC) were characterized by …

A new adsorbent modified from wheat residue was synthesized after reaction with
epichlorohydrin and triethylamine by using the modifying agents of diethylenetriamine in the …

Alkali treated tea waste (ATTW) was investigated as a novel alternative cost-effective natural
adsorbent to decontaminate the pollutant of chromium (Cr (VI)) in the polluted water with the …

In this study, bio-chars were evaluated as a potential adsorbent for the removal of Cr (VI)
ions from aqueous solutions. The effects of some important parameters including initial pH …
