Sažetak
This study examined adsorption of anionic dye on four zeolitic materials incorporated (VS-1, CuZSM-5) and not incorporated into metals (S-1, ZSM-5). The adsorption of the bromothymol blue (BTB) dye on the four adsorbents was analysed using isotherm models Langmuir, Freundlich, and Temkin. Two kinetic models were also applied to study the adsorption process, pseudo-first order and pseudo-second order. The isothermal data showed good correlation. The kinetics of adsorption were better described by the pseudo-second order model. The results obtained indicate that the maximum percentage removal of the BTB dye was given by a purely non-incorporated silicic zeolite (S-1).
