Nanobiocatalyst beds with Fenton process for removal of methylene blue

Abstract The remediation of methylene blue from wastewater using chitosan-sunflower-nano-iron (CSN) beds was examined in this study with the Fenton process. Nano-iron is synthesized green synthesis Then, biopolymer obtained nano-iron, sunflower tray waste, and chitosan. These used process for removing Methylene (MB) water. Beds dye are characterized SEM, TEM, FTIR, XRD techniques. For method optimization, effects concentration, temperature, pH, H 2 O , amount biocatalyst were studied. result wavelength scan found 660 nm dye. Using CSN, catalyst very effective color removal MB under optimal conditions. highest rate 98% at pH 6 270 min. optimum conditions as follows; concentration: 25 mg/L, absorbent: 2.5 mg/mL, temperature: 60 °C, amount: 20 mg/L (600 µL, 30%). When experiment studied conditions, max. calculated to be 98%. From XRD, FTIR results, change surface could clearly observed. It understood that results we easily removed a large (MB).
