To this end, pyrene was sorbed
from its 2x[10.sup.-5] g/L aqueous solutions with various solvent contents onto CDA films and the fluorescence spectra of the probe in the solid phase of the matrices were recorded.
where [k.sub.2] (g/mg/min) is the pseudo-second-order rate constant, [q.sub.e] is the amount of arsenic sorbed
(mg/g) at the equilibrium, and [q.sub.t] is the amount of the sorption at any time t (min).
[C.sub.e] is the concentration of the Cr(VI) solution (mg/L) at equilibrium, [q.sub.e] the amount of Cr(VI) sorbed
per unit weight of sorbent (mg/g) and [K.sub.L] is the constant related to the free energy of adsorption (L/mg).

 is given as under:where sorbed
concentration of metal ions on resin(molg-1) at time 't' was plotted verses (t)1/2, andgave 9.1 min for Ni (II) and 10.6 min for Cu (II) withthe co-efficient of correlation 0.979 and 0.994 for these metal ions, but deviated when the agitation timebecame some higher (Fig.
Edwards proposed that the sorbed
surfactant enhanced HOC sorption not only through increasing OC content of the sorbent, but also acting as an effective sorbent for HOCs .
Figure 3 showed that the order of the As (V) specifically sorbed
was Mode A > Mode B > Mode C while the order of the As (V) associated with amorphous and poorly crystalline hydrous oxides of Fe was Mode C > Mode B > Mode A.
Indeed, from the beginning of the curves to the breakthrough points, the inlet lead ions are totally sorbed
instead of the proton ions previously fixed.
The amount of Cd sorbed
by soil ([C.sub.s]) was calculated as the difference between the amount added and the amount in the equilibrium solution.
Major portion of P (%) was sorbed
within one day's incubation period (24 hours).
The original hypothesis was that the rods sorbed
moisture from the wood surrounding the hole, thereby reducing moisture and the ability of the boron to diffuse into the wood.
By simulating multiple events on an Al/Fe material over a period of several days, we have observed significant increases in sorption capacity during intervals between leaching events that were attributed to sorbed
P being converted to more strongly bound forms--a process that resulted in more sorption sites becoming available prior to the next leaching event (Hsieh et al.
