Removal of basic dye from aqueous solution using tree fern as a biosorbent

Adsorption of Methylene Blue from Aqueous Solution Using Steam-Activated Carbon Produced from <i>Lantana camara</i> Stem

“…The Langmuir constant "b" and "Q o " were calculated from this isotherm and their values are given in Table 1. Conformity of the experimental data to Langmuir isotherm model indicates the homogenous nature of SALC similar observations were reported on the adsorption of Cd onto Crysophyllum albidum shell [29]. The essential characteristics of the Langmuir isotherm can be expressed in terms of a dimensionless equilibrium parameter (R L ) [35], which is defined in Equation (3) as.…”

“…It followed the predicted pattern of increasing percentage adsorption as the dosage was increased [28]. This is probably because of the resistance to mass transfer of dye from bulk liquid to the surface of the solid, which becomes important at high adsorbent loading in which the experiment was conducted [29].…”

Efficacy of mangrove leaf powder for bioremediation of chromium (VI) from aqueous solutions: kinetic and thermodynamic evaluation

“…Most of the low-cost sorbents have the limitation of poor sorptive capacity, and thereby, for the same degree of treatment it generates more solid waste (pollutant laden sorbent after treatment) leading to disposal problems. Therefore, there is a need to explore low cost, economically viable and effective sorbent, having high pollutant sorption capacity (Ho et al 2005).…”

Adsorption of Methylene Blue from Aqueous Solution on High Lime Fly Ash: Kinetic, Equilibrium, and Thermodynamic Studies

“…[10,11] Activated carbon has excellent adsorption capacity for dyes but its uses remains limited, because of high cost. Therefore, many investigators have studied to use lower-cost and readily available adsorbents to remove dyes from aqueous solutions such as activated bleaching earth, perlite, seashells, rosewood sawdust, sugar industry pulp, sugar cane dust, tree-fern, peat moss, and natural sediment, [12][13][14][15][16][17][18][19][20] as alternatives to activated carbon.…”
