        Preparation of a fly ash-based geopolymer for removal of a cationic dye: Isothermal, kinetic and thermodynamic studies

        Ozkan Acisli,Ilker Acar,Alireza Khataee 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.83 No.-

        A class Ffly ash-based geopolymer was prepared for the removal of Basic Yellow 2 (BY2) from aqueoussolutions. The geopolymerization process transformed the sphericalfly ash particles into a porous andamorphous polymeric structure, sodium-alumina-silicate hydrate gel. The removal efficiency increasedwith the geopolymer dosage while it decreased with BY2 concentration. Specifically, the efficiency of94.47% was achieved with the geopolymer dosage of 2.0 g L-1. However, further increases resulted in asubstantial reduction, down to 57.76% for 3.0 g L-1. At 293 K for 300 min, the efficiency decreased from84.69 to 64.19% for BY2 concentrations of 10 and 50 mg L-1, respectively. Based on the isothermal, kineticand thermodynamic investigations of the adsorption process, the Langmuir and Temkin models wellcorrelated with the obtained results. The adsorption occurs spontaneously and shows endothermiccharacter. The pseudo-second order and the intra-particle diffusion models are valid for 293 K while theadsorption results well suited with the pseudo-second order for 313 and 323 K. In conclusion, thepreparedfly ash-based geopolymer provided favorable results for the removal of Basic Yellow 2 fromaqueous solutions.
