Abstract
Dye removal processes have gained importance with the developing industries. Among these, the fenton process, known as one of the advanced oxidation processes, is also very important today. In our research, the bionano-fenton catalyst was prepared by attaching nano iron to the polymer prepared using sunflower and chitosan, which are biological materials. Subsequently, using this reagent, it was aimed to remove DB 15 dye from water and this procedure was investigated. For this purpose, determination of optimum time, pH, temperature, fenton reagent and catalyst amounts for dye removal was studied. In addition, different techniques were used to examine the interactions between the obtained bionano-fenton reagent and the dye. In dye removal studies, the maximum absorbance of the dye was found by scanning it with a 598 nm spectrophotometer. In addition, using this method and calculations, optimum time: 15 min., pH: 2 temperatures: 25oC, H2O2 amount: 600 uL (30%), and catalyst amounts were determined as 60 mg/L. It has been shown that 95.89% of the paint can be removed from the environment by using this method. In addition, changes occurring before and after dye removal were explained by SEM, TEM and photographs.
