Abstract High concentrations of reactive dyes in receiving waters pose a danger to the ecosystem due unique properties such as high alkalinity and strong structural stability, which distinguish them from other dyes. This study aims investigate efficiency sono‐catalytic process combined with activated carbon/Fe 3 O 4 persulfate (PS/US/AC‐Fe ) removing blue 19 dye (RB 19) aqueous solutions well optimize factors influencing removal efficiency. Activated carbon (AC) was prepared worn‐out tires Fe synthesized using co‐precipitation. The optimization experiments data analysis for RB conducted Box Behnken Design (BBD). optimal values pH, initial concentration, persulfate(PS)dosage, composite dosage, reaction time were determined be 3.1 mg/L, 22.4 1.34 g/L, 1.75 90 minutes, respectively. Based on variance experimental results various models, second‐order kinetic model correlation coefficient ( R 2 = 0.9685) (Rajd 0.9432) selected estimating PS/US/AC‐Fe process. percentage chemical oxygen demand (COD) found 68% under optimum conditions. Considering these results, this method can applied treat wastewater industries that produce combinations.

Efficient Removal of Emerging Contaminant Sulfamethazine in Water by Fe₂O₃: Roles of Morphological Features and Oxygen Vacancies

Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(3)

Published: Feb. 16, 2025

ABSTRACT The inability to recycle Fenton reagents and a narrow pH range restricts hematite (Fe 2 O 3 ) application in the actual photo‐Fenton system. engineering of surface structures is identified as an effective approach for enhancing activity material. In this work, three different morphologies (nanosheet, cube, ring) Fe materials containing oxygen vacancies (OVs) were synthesized by hydrothermal method, novel system degradation sulfamethazine was examined. presence oxalic acid, /oxalic acid heterogeneous catalytic demonstrated situ generation H facilitated Fenton‐like reactions. as‐prepared nanosheet‐Fe showed highest efficiency. free radical capture experiment investigated using sacrificial agents, results suggested that superoxide radicals principal active species involved. Ecotoxicity assessments utilizing toxicity prediction software assessed reaction intermediates generated during via quantitative structure–activity relationship indicating these exhibited reduced developmental toxicity. possible pathways mechanism synergistic effect between proposed. This research presents strategy design synthesis photocatalysts with various vacancies, suitable catalysis related environmental contexts.
