Özet:

Synthetic paints attract a lot of attention due to the width of their usage areas and the amount of excessive use. Particularly, the damage caused to the water by the part remaining from the paint used and disposed of in the environment is visible from time to time. Removal of synthetic dyes used from these waters is an important research topic. In our research, we planned to investigate the removals comparatively by using the biosorbent we developed in different combinations. Therefore, chemo-biosorbent was obtained by modifying it with biosorbent and nano-iron produced from sunflower and chitosan, and a reaction medium was created using Methylene Blue (MB), Direct Blue 15 (DB) and Reactive Black 5 (RB) dyes. In addition, dye removals of chemosorption, biosorption, Reactions with UV combined methods under the same optimum conditions were compared to find out which removal was most appropriate. As a result of the reaction, it was observed that UV application contributed significantly to the experimental conditions. It was observed that UV increased the dye removal at varying rates in the range of 0.27-4.42% biosorption and Fenton reactions. Accordingly, it was understood that UV did not have a positive contribution in the chemobiosorption reaction, which we performed using nano-iron in its structure. Considering the cost evaluation, such studies will contribute to the selection of the preferred method for dye removal.
