Adsorption of bromothymol blue (BTB) dye using four zeolites as adsorbent

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