Abstract

This study investigated the performance of zeolitepolyaniline
nanocomposite (ZPC) in the removal of Reactive Red 2 (RR2) dye from aqueous solution in a fixed-bed adsorption column. This work evaluated the effect of column aspect ratio, bed loading, flow velocity and initial concentration on the RR2 dye removal efficiency. The concentration-time profile of the treated effluent stream was expressed as breakthrough curves (BTC). The BTCs showed a steep slope with a short tail, characteristic of rapid surface
reaction and dispersion effects, respectively. The adsorbent media had a dynamic adsorption capacity of 68 mg/g (at 5 mL/ min, 298 K
and 100 mg/L RR2) that is quite competitive in comparison to other
adsorbents.
