Abstract
In this study, the effectiveness of amberlite IRA-938 resin for Rose Bengal (RB) dye removal from aqueous phase was evaluated. For the RB dye removal, equilibrium was achieved within 45 min because rate of adsorption was fast. The adsorption equilibrium for RB dye onto amberlite IRA-938 resin was in good agreement with Langmuir adsorption isotherm. It was observed that amberlite IRA-938 resin had excellent RB dye adsorption capacity (qm = 142.86 mg g−1 at 23°C). The environmental applicability of amberlite IRA-938 resin was performed in the separation of RB dye from the tap water sample spiked with 50 mg L−1 RB dye solution. The breakthrough and exhaustive capacity were 100 and 325 mg g−1, respectively.
