Removal of Industrial Dye via Biohybrid Composites Characterized by FTIR and SEM

ABSTRACT
Background and Objective: Dyes that discharge from the industries are very toxic even at very minimum concentrations. Consequently, the exclusion of the dyes is very essential from waste water. Therefore, this study was designed to remove the synthetic dye by using bio-hybrid composites. Materials and Methods: Bio-hybrid composites MUS-ZnO-PANI (mustard zinc oxide polyaniline) and MUS-ZnO-PPy (mustard zinc oxide polypyrrole) were synthesized for dye exclusion via using the adsorption method. An experiment was performed under different optimized conditions. To find surface morphology, functional groups, active binding and thermal stability FTIR and SEM techniques were used. Results: For all types of biosorbents maximum removal of AAR-5 (Act acid red 5) dye observed at 2 pH and the level of dosage was 0.05 g/50 mL. While the equilibrium achieved in 60-90 min with maximum absorption capacity. A suitable temperature to exclude the dye was observed and that was 35°C. Conclusion: After this study, it was concluded that the elimination of the dye effluent from waste water is important to keep the environment healthy. The results of this study proved that the adsorption method is an economical technology for the exclusion of dye from waste water.
