Heavy metal pollution is one of the most pervasive environmental problems globally. Novel
finely tuned algae have been proposed as a means to improve the efficacy and selectivity of …

Arsenic and antimony are metalloids, naturally present in the environment but also
introduced by human activities. Both elements are toxic and carcinogenic, and their removal …

Biochar has become a popular research topic in sustainable chemistry for use both in
agriculture and pollution abatement. To enhance aqueous Cr (VI), Pb (II) and Cd (II) removal …

Biosorption was carried out in this study using the biomass of microalgae Scenedesmus sp.
as adsorbent for the removal of hexavalent chromium or Cr (VI) from solution. Different …

This study focused on the sustainable removal of chromium in its hexavalent form by
adsorption using sugar-extracted spent marine macroalgal biomass–Ulva prolifera. The …

Sulfidation of nanoscale zerovalent iron (nZVI) has attracted increasing interest for
improving the reactivity and selectivity of nZVI towards various contaminants, such as …

Bio-composite of mango (Mangifera indica) was prepared and employed for Cr (VI)
adsorption from aqueous media. The effect of various process variables ie, pH, Cr (VI) ions …

Heavy metals from industrial effluent are major threat to environment because of their major
toxicity effect. The treatment of metal contaminated wastewater is of special concern. This …

Biochar adsorbents can remove environmental pollutants and the remediation of Cr (VI) and
nitrate are considered. Cr (VI) is a proven carcinogen causing serious health issues in …

Water pollution by human activities is a global environmental problem that requires
innovative solutions. Arsenic and chromium oxyanions are toxic compounds, introduced in …
