Textile wastewater heavy metal pollution has become a severe environmental problem
worldwide. Metal ion inclusion in a dye molecule exhibits a bathochromic shift producing …

Chromium is a potentially toxic metal occurring in water and groundwater as a result of
natural and anthropogenic sources. Microbial interaction with mafic and ultramafic rocks …

Certain five heavy metals viz. arsenic (As), cadmium (Cd), chromium (Cr)(VI), mercury (Hg),
and lead (Pb) are non-threshold toxins and can exert toxic effects at very low concentrations …

Extensive industrial activities resulted in an increase in chromium (Cr) contamination in the
environment. The toxicity of Cr severely affects plant growth and development. Cr is also …

The biosorption process has been established as characteristics of dead biomasses of both
cellulosic and microbial origin to bind metal ion pollutants from aqueous suspension. The …

Groundwater resources in California represent a confluence of high-risk factors for
hexavalent chromium contamination as a result of industrial activities, natural geology, and …

Biochar-supported nanoscale zero-valent iron (nZVI) produced under different temperatures
was studied to evaluate the effect of the nZVI-biochar composite on the removal of …

Redox processes mediated by biochar (BC) enhanced the transformation of Cr (VI), which is
largely dependent on the presence of PFRs as electron donors. Natural or artificial dopants …

Hexavalent chromium is a heavy metal used in a variety of industrial applications which is
highly toxic to humans, animals, plants and microorganisms. Moreover, it is a well …

Naturally occurring Cr (VI) has recently been reported in ground and surface waters. Rock
strata rich in Cr (III)-bearing minerals, in particular chromite, are universally found in these …
