Treatment of Textile Wastewater Using Biochar Produced …

proved to be an outstanding material for treating the cationic dye namely methylene
blue dye present in the effluent [15]. Biochar obtained from waste chicken bones
proved itself to be an excellent material for eliminating rhodamine B dye [16]. The
biochar derived by using a variety of crop residues showed better results which was
extremely very helpful in the elimination of methyl violet dye present in wastewater
[1]. Agricultural waste namely sunflower seed hull rejected from food industry upon
further processing was further made use of to extract methyl violet dye from aqueous
solution [17]. Biochar produced by using agricultural waste namely rice husk was
used to get rid of the reactive black dye which is present in textile effluent [18]. Agricultural squander rice straw was converted into a biochar by pyrolysis method, and
this biochar was further activated, and the final product was used to adsorb methylene blue and crystal violet dye [19]. Pomelo peel waste was scrap, and this material
was further activated to eliminate methyl orange dye [20]. The biochar derived from
persimmon fruit peel was used to adsorb basic blue dye from aqueous solution, and
this biochar proved to be a promising adsorbent material [21]. The elimination of
Basic Blue 41 and Basic Red 09 dyes was studied by making use of biochar derived
from groundnut pod. The biochar was obtained by pyrolysis method [3]. Biochar
extracted from coffee husk showed excellent sorption capacity towards the termination of variety of dyes present in wastewater. This biochar was acquired by pyrolysis
method at a temperature of 450 °C, and it was further exposed to chemical activation
[22]. Biochar extracted from agricultural waste namely corn cob was used to get
rid of the methylene blue dye present in wastewater. The biochar was achieved by
following pyrolysis technique in which the corn cob sample was pyrolysed at 500 °C
for 2 h [8]. Agricultural waste proves to be a low-cost-effective adsorbent for eliminating any toxins present in the wastewater. By taking into consideration, cocoa pod
husk as a source of agricultural waste biochar was acquired by pyrolysis method.
This cocoa pod husk after getting pyrolysed at 550 °C was then subjected chemical
activation, and the final puce product obtained was used to eliminate dyes present in
the textile effluent [23]. Biochar obtained from milled raw grass straw confirmed that
it can be used as an adsorbing material for the removal of methylene blue dye. This
biochar from straw underwent certain chemical modifications to enhance the adsorptive capacity of the material. Pyrolysis technique was adopted to derive biochar from
the agricultural waste, and this method was carried out in the presence of nitrogen
flow [24]. Biochar was got from pine cone by choosing pyrolysis method. The biochar
was obtained at a temperature of 500 °C. This eco-friendly biochar adsorbent showed
excellent removal capacity of methylene blue dye [25]. Crab shell was found to be a
good source of squander and the biochar derived from crab shell showed extraordinary sorption capacity towards both anionic and cationic dyes namely congo red and
malachite green [26]. The biomass from eucalyptus bark was further processed, and
this in turn resulted in biochar which was employed to eliminate the MB dye [27].
An agro waste namely bael shell was made use of to produce biochar which in turn
was found to be used in treating wastewater which had a high concentration of patent
blue dye associated with it. This biochar was obtained on pyrolysing the bael shell
at a temperature of 500 °C [28]. A low-cost squander peanut shell was subjected
to KOH activation and the resulting biochar found its application in the removal of
