abstract = "In the present study, a polyaniline/carboxymethyl
cellulose/TiO2 nanocomposite (PAn/CMC/TiO2) was
synthesized by a polymerization method, and was used
for adsorption of Congo Red from aqueous solution. The
effects of operational parameters of the adsorption
process including pH, initial dye concentration,
temperature, adsorbent dosage, and adsorption time on
adsorption efficiency were investigated, and response
surface methodology was used for their optimization.
Optimal adsorption conditions were determined at pH of
2.6, initial concentration of 82mgL, temperature of 56
degreeC, adsorption time of 24a min, and adsorbent dose
of 0.14a g. In addition, the system was also simulated
using artificial neural network (ANN) and genetic
programming (GP). It was found that the behavior of the
system could be well predicted by ANN using 5, 1 and 8
neurons for input, middle and output layers,
respectively. Kinetic and isothermal analyses showed
that the maximum adsorption capacities were obtained at
94.28, 97.53 and 119.9 mgg by Langmuir model at
temperatures of 25, 40 and 50 degreeC, respectively and
that adsorption kinetics followed the
pseudo-second-order model. The nano-adsorbent was also
found to be reusable without a significant change in
adsorption capacity for at least five
adsorption-desorption cycles. Finally, the mechanism of
dye adsorption on the nano-adsorbent was investigated
and proposed",
