Adsorption studies on treatment of textile dyeing industrial effluent by flyash

Grass waste: A novel sorbent for the removal of basic dye from aqueous solution

“…This was because when the initial concentration increased, the mass transfer driving force would become larger, hence resulting in higher MB adsorption. Similar trend was obtained in the adsorption of MB on flyash [25] and also commercial activated carbon [26].…”

Removal of methylene blue from aqueous solution using cotton stalk, cotton waste and cotton dust

“…For example, when the initial MB concentration increases from 25 to 100 mg/l, the equilibrium sorption capacities of CS, CW and CD increase from 1.96 (39.20%) to 5.95 mg/g (29.75%), from 2.50 (50.0%) to 14.04 mg/g (70.20%) and from 3.10 (62.0%) to 15.78 mg/g (78.90%), respectively. Similar trends have also been observed for methylene blue sorption onto bamboo-based activated carbon [23], and fly ash [24]. When initial MB concentration increases from 25 to 100 mg/l, the percent removals of MB by CW and CD increase from 50.0% to 70.20% and from 62.0% to 78.90%, respectively.…”

Adsorption of methylene blue on low-cost adsorbents: A review

“…Though commercially available activated carbon (CAC) are usually derived from natural materials such as biomass, lignite or coal, but almost any carbonaceous materials may be used as precursor for the preparation of carbon adsorbents [43][44][45][46][47][48][49][50][51][52], because of its availability and cheapness, coal is the most commonly used precursor for activated carbon production. Coal is a mixture of car- [56,57] with success for dye removal.…”
