چکیده
|
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 (δg^o) and enthalpy changes (δh^o). considering the negative δg^o and positive δh^o, ab62 adsorption on ppy/mcm-41 nanocomposite can be considered a spontaneous, endothermic reaction.
