Abstract
In this paper, we aimed to evaluate Acid Blue 62
removal from aqueous media, using mesoporous silicate
MCM-41, loaded with polypyrrole (PPy) and polyaniline
(PAni) composites. PPy/MCM-41 nanocomposite showed
higher performance than PAni/MCM-41 due to its smaller
molecule size. For characterizing the synthesized composites,
different methods were applied. The Langmuir
model showed the greatest agreement with the experimental
findings (qm, 55.55 mg g-1). The kinetic study also
confirmed the compatibility between the pseudo-secondorder
model and adsorption. Moreover, we measured Gibbs
free energy changes (DGo) and enthalpy changes (DHo).
Considering the negative DGo and positive DHo, AB62
adsorption on PPy/MCM-41 nanocomposite can be considered
a spontaneous, endothermic reaction.
