“…Also, in alkaline environments Cr(III) can oxidize to Cr(VI), which is toxic even at low concentrations, as it induces coetaneous allergies and is carcinogenic over long exposures [4,5].Various methods developed for removal of toxic metals from groundwater include: isolation and containment, mechanical separation, pyrometallurgical separation, chemical treatment, permeable treatment walls, electrokinetics, biochemical processes, phytoremediation and soil flushing [1]. Chemical remediation using naturally occurring biodegradable biomass has generated a great deal of interest due to its low cost and high efficiency [6]. Some of the sorbents based on biomass are bark, seaweed, leaf mould and chitosan; detailed information on these and a comparison of their chemistry and performance can be found in work of S.E.…”
