The present study highlights about adsorption of Hexavalent
Chromium from Wastewater Utilizing Chitosan Based Activated Carbon Prepared
from Butea monosperma Bark. Waste water from many industrial operations
contains hexavalent chromium metal ions, which worsen environmental
degradation. The literature contains documentation of common physical and
chemical treatment methods for getting rid of hexavalent chromium. Not only are
these methods costly and energy-intensive, but they also seem to produce a
build-up of potentially dangerous byproducts. The current study used
chitosan-coated Butea monosperma bark-activated carbon to extract hexavalent
chromium from an aqueous solution. The batch experiment was used to investigate
the pH effect, time of contact with the adsorbent, adsorbent dose, and the
starting concentration of Cr (VI) ions. The pH of the biosorbent was found to
be optimum at three for Cr (VI) sorption. The elimination of Cr(VI) from the
solution will be accelerated with the rise of contact time. Up to 94% more Cr (VI) can be extracted for
every unit increase in adsorbent dose. As the blood level of Cr (VI) increased,
so did the clearance rate. In this study, researchers discovered that a
pre-treated biosorbent was an excellent material for eliminating Cr(VI) ions
from contaminated water. The final results revealed up to a 73% reduction in
percentage elimination of Cr(VI). Adsorbents have confined a wide variety of
active sites to saturate at a certain concentration, which justifies this
result.
