MB dye, and it showed a good sorption capacity [29]. Arjun fruit was used for the
production of biochar. Biochar was obtained by pyrolysing the fruit at 500 °C for
3 h, and the obtained biochar was employed to remove the congo red dye from the
effluent [30]. Cassava slag was used to treat aqueous solution containing Rhodamine
B and the biochar obtained from this cassava slag by hydrothermal carbonization
technique. This biochar also showed tremendous adsorption capacity, and it was
utilized for treating a variety of dye solution [7]. Strychnos potatorum seed powder
showed good sorption capacity towards the elimination of methylene blue dye [31].
Orange peel was taken as a source of agricultural waste, and orange peel was further
activated by using sulphuric acid. The activated powder had good pore characteristics, and this low-cost eco-friendly material was widely employed to eliminate MB
dye present [32]. Adsorption studies were carried out by utilizing raw tamarind seeds
and surface modified tamarind seeds. The surface modification was done by using
sulphuric acid. The tamarind seeds obtained from kitchen waste should outstanding
performance towards the removal of methylene blue dye solution [33]. Adsorption
of methylene blue dye onto cashew shell proved to be very significant in which the
cashew shell was surface modified to enhance the pores within it which facilitated
the number of vacant sites available for the process of adsorption to take place [34].
The activated carbon or the biochar obtained from corn cob by following microwave
assisted pyrolysis proved to be a low-cost and eco-friendly adsorbent which played
a major role in getting rid of the MB dye present in aqueous solution. The sorption
process was spontaneous and exothermic in nature [5]. Microwave assisted pyrolysis technique was applied to the agricultural waste material namely saw dust. The
biochar obtained as a result of pyrolysis was further used for the separation of dye
solution present in the aqueous solution [2]. Cashew nut shell modified with sulphuric
acid was used to extract all the pollutants present in wastewater. Surface modification
increased the number of vacant site available in the bisorbent [35]. Adsorption of
pollutant from aqueous solution using sulphuric acid modified Caryota urens seeds
was explained [36]. A most facile methodology was adopted for the evacuation of
pollutants present in aqueous solution. Coffee bean was further treated, and the activated carbon was derived which in turn was used for the recovery of pollutants [37].
A novel and very effective type of low-cost adsorbent namely S. potatorum seeds was
surface modified, and this material helped in expelling the pollutant from aqueous
solution. The surface modification was observed using FTIR and SEM analyses [38].
A study affirmed that hydrothermal carbonization of urban food waste was utilized
to produce biochar, and this biochar was very helpful to eliminate Acridine Orange
and Rhodamine 6G dyes from adulterated water [39]. A low-cost-effective adsorbent
obtained from tomato waste was used to evacuate pollutants present in aqueous solution. Carbonization technique was employed to obtain biochar from tomato waste
[40]. Hydrothermal conversion and pyrolysis method were employed to produce
biochar from various agricultural wastes like pinewood, peanut shell, and bamboo
biomass. The biochar obtained from pyrolysis method yielded a good result than
that of HTC method. The biochar obtained from the above-mentioned agricultural
waste was significantly effective in eliminating the methylene blue dye present in
wastewater [41]. Two different fruit shells namely Rutaceae vila and Vilvam fruit
