Background and Objectives: Dyes are one of the main environmental pollutants in the industrial effluents including textile industries, which are harmful for human health and environment. The purpose of this research was to investigate removal efficiency of Reactive Black 5 (RB5) dye using adsorption onto strongly basic anion exchange resin as an appropriate adsorbent.
Materials and Methods: After preparing materials and equipment required, removal efficiency of Reactive Black 5 (RB5) dye using adsorption onto strongly basic anion exchange resin was investigated with respect to the variation of pH, contact time, adsorbent dosage, and initial RB5 dye concentration in batch system. Then results were analyzed using Excel software.
Results: Our results showed that removal efficiency was decreased by increasing pH and initial RB5 dye concentration. Moreover, we found that the removal efficiency was increased by increasing adsorbent dosage and contact time. The kinetics and equilibriums data were explained acceptably by Langmuir isotherms and pseudo-second-order kinetics models respectively.
Conclusion: Overall, our findings revealed that removal of RB5 dye from aqueous solution using adsorption onto strongly basic anion exchange resin can be considered as an effective and quick method.
