| dc.description.abstract | Cobalt and nickel doped catalysts were synthesized by using chitosan and alginate and used in the degradation of Remazol Yellow 4GL (RY) and Remazol Black B (RB) dyes. XRD pattern of catalysts exhibited that amorphous and semi-crystalline form for CoNi-chitosan and Co-alginate, respectively. SEM images showed catalyst's surface was rough, grainy and rod-like structures. The surface functional groups were determined by FTIR analysis method and it was seen clearly presence of alginate and chitosan. The Co-alginate catalysts exhibited higher dye degradation (74% for RY) and lower reaction time (6 min for RB). The reduction reaction was in good agreement with pseudo-first-order kinetic model and reaction rate constant was determined as 0.140 min-1 and 0.174 min-1 for RY and RB, respectively. The RY reduction percent over both catalysts was higher than RB. Co-alginate showed approximately 70% reduction efficiency for RY even after 4 runs. The dye reduction efficiency and catalytic activity of the catalysts were promise for organic pollutant dyes catalytic reduction applications. | |
