Fast and effective removal of textile dyes from the wastewater using reusable porous nano-carbons: a study on adsorptive parameters and isotherms

Efficient cationic dye removal from water through Arachis hypogaea skin-derived carbon nanospheres: a rapid and sustainable approach

“…Carbonaceous adsorbents are generally prepared from different biomass and agricultural wastes due to their many benets, including renewability, affordability of the precursor, and environmental friendliness. 19 Agricultural waste and biomass materials such as garlic peel, 20 areca nuts, 18 oil palm leaves, 21 onion peel, 22 etc., were frequently used as cost-effective biosorbents for eliminating cationic dyes by synthesizing CNSs from these precursors. Apart from these, a few other carbon materials derived from forestry residues, food processing waste, and agricultural waste are also used in dye removal applications such as oil palm ber-based activated carbon, 23 watermelon peel biochar, 24 pea peel biochar, 25 mandarin peels, 26 carbon derived from neem bark, 27 raw walnut shell-based activated carbon, 28 groundnut shell powder, coconut coir powder and activated corn leaf carbon, 29 etc.…”

“…Moreover, biowaste-derived CNSs have distinct advantages as they provide a sustainable, environmentally friendly, and easy synthesis approach option that makes use of agricultural byproducts that would otherwise go to waste, as reported in earlier research. [18][19][20][21][22] Biomass-derived CNSs have inbuilt porosity being mesoporous in nature with spherical morphology, making them an ideal candidate for dye degradation applications. Furthermore, the renewable nature of biowaste provides a steady and plentiful supply, decreasing reliance on nite resources.…”
