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
Removal efficiency (%) started decreasing after 293.0 K because at high temperature motion of MB molecules increased and contact time between adsorbent and adsorbate
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 .
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.
