where [q.sub.e] (mg/g) is the amount of dye adsorbed per unit mass of adsorbate at equilibrium, [C.sub.e] is the concentration of the adsorbate left in the solution (mg/L), [K.sub.f] is the adsorption capacity at unit concentration, and 1/n is the adsorption intensity.
In Table 3 the value coefficient ([R.sup.2]) for adsorption isotherms for MB and phenol were best fit for the Freundlich model, which enables multilayer adsorbate adsorption with weak interactions between adsorbate and adsorbent.
Removal efficiency (%) started decreasing after 293.0 K because at high temperature motion of MB molecules increased and contact time between adsorbent and adsorbate decreased.
The quantity of adsorbate adsorbed in the equilibrium state, ([q.sub.e], mg.[g.sup.-1]) and the dye removal efficiency (De, %) were determined using Equations (2) and (3), respectively.
With respect to a lower influent As(V) concentration, the inflow adsorbate molecules were adequate to the active sites on the surface of the adsorbent.
The high affinity of the adsorbate to adsorption sites (physical adsorption or ion exchange) was associated with the higher sorption rate at initial times [34].
where [q.sub.e] and [C.sub.e] represent the adsorption capacity (mg/g) of the adsorbent and the concentration of adsorbates (mg/L) at equilibrium, respectively.
(2014) observed optimum removal efficiency of reactive blue 114 dye at 90 min of contact between adsorbate and adsorbent (pomelo peel) and Irem et al.
As relative humidity goes up, the material goes from single-layer adsorbate transport to multiple-layer adsorbate transport to internal capillary condensation to free water capillary suction and, finally, to supersaturated flow.
The rate of adsorption and the mechanism of adsorbate--adsorbent interaction depends on the ionic nature of adsorbate and adsorbent surfaces.
Adsorption capacity of methylene blue (dye) and 4-chlorophenol were determined as function of adsorbate initial concentration and adsorbent dosage.
