Artocarpus camansi adsorbed 1 with q max values of 409 mg g
À1 according to
Langmuir adsorption isotherm under pH 4.8. Rapid kinetics of 1 with a pseudosecond-order kinetics model suggested provided an alternative biosorbent to obstruct
dyes from wastewater (Lim et al. 2017; Lim et al. 2016).
In the same way, coconut husk and activated carbon adsorbed cyanosine from the
aqueous solutions following Langmuir adsorption isotherm and Freundlich adsorption isotherm models with first-order kinetics. Batch studies advocated 86 and 98%
dye adsorption by coconut husk and activated carbon with a decrease in chemical
oxygen demand from 1650 to 215 mg L
À1 after adsorption by coconut husk, proving
an environmentally benign and low-cost adsorbent (Gupta et al. 2010). Cucumis
sativus fruit peel adsorbed Acid Red 1 dye from textile wastewater with q max value of
18.76 mg g
À1 following Langmuir adsorption isotherm and Dubinin-Radushkevitch
isotherm models thus showcasing Cucumis sativus fruit peel as an effective and
cheap adsorbent for industrial wastewater treatment (Khanna and Rattan 2017).
Moreover, Cucumis sativus fruit peel also adsorbed 1 from wastewater showing
pseudo-second-order kinetics while spontaneity and exothermicity were evident
from negative values of ΔS
and ΔH
(Shakoor and Nasar 2017).
Agricultural solid waste activated by sulfuric acid was employed to remove
crystal violet (7) and Rhodamine B (9) from aqueous solution. Langmuir adsorption
isotherm provided the best relativity for isotherm data to adsorb 7 and 9 onto the
activated solid waste (Smitha et al. 2017). The applicability of Cucumis sativus fruit
peel waste as a cheap biosorbent was evaluated by optimizing various reaction
parameters. The comprehensive isotherm analysis showed that the crystal violetCucumis sativus fruit peel system correlated with Langmuir adsorption isotherm
model having q max of 149.25 mg g
À1 . The kinetic and thermodynamic results
showed pseudo-second-order and endothermic nature, respectively (Shakoor and
Nasar 2019).

C. The pseudosecond-order kinetics was obeyed, and thermodynamics process was endothermic
(Dahri et al. 2016). Durian rind powder, an agricultural waste material, also adsorbed
1 (95.91%) and brilliant green (87.46%) dyes effectively, and data correlated to
Langmuir adsorption isotherm model well (Nuithitikul et al. 2010; Anisuzzaman
et al. 2015).
Similarly, activated carbon produced from durian seeds effectively removed
remazol brilliant blue reactive dye from water in the batch process. Adsorption
data correlated to the Freundlich adsorption isotherm model with the highest
removal capacity at pH 2 (Ahmad et al. 2015a). Similarly, chemically modified
durian seed with activated carbon also exhibited prominent adsorption of 2 in a batch
process by keeping in mind various parameters. Adsorption conformed Freundlich
