abstract = {A study was conducted on batch and column
competitive adsorption of fluroxypyr (FLX) and tannic acid
(TA) from distilled (DW) and tap water (TW) on activated
carbon cloth (ACC) and granular activated carbon (GAC).
Thermal desorption of the adsorbates from the spent ACC
was also studied. FLX adsorption was higher from TW than
from DW at low FLX equilibrium concentrations, and the
inverse was observed at high FLX concentrations. The pres-
ence of TA diminished the amount of FLX adsorbed from
both solvents due to partial blocking of the microporosity,
but the same trends as before were observed at low and high
FLX concentrations. Carbon consumption, obtained from
the breakthrough curves, was lower as a function of superfi-
cial contact time with ACC than with GAC. The presence of
TA increased carbon consumption, which was related to the
microporosity of the adsorbents. Thermal desorption pro-
files of the spent ACC showed two peaks and one peak af-
ter adsorption from DW and TW, respectively. Desorption
peaks shifted to higher temperatures with an increase in the
heating rate, allowing the apparent activation energies an pre-exponential factors of the desorption processes to be de-
termined},
