Dissolved Oxygen Changes in Wastewater During Sulfamethoxazole Degradation by Photo-Fenton Treatment

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3333 - 3333

Published: April 9, 2025

This study examines the degradation of sulfamethoxazole (SMX) in water using photo-Fenton process, focusing on dissolved oxygen (DO) dynamics, organic matter mineralization, and quality improvement. The results show that SMX follows a rapid kinetic pattern, achieving complete removal within 30 min. However, total carbon reduction occurs more gradually, indicating persistence intermediates before full mineralization into CO2 H2O. DO evolution biphasic trend: an initial decline due to oxidative consumption, followed by increase H2O2 decomposition O2. Initially, at [H2O2]0 ≥ 3.0 mM, sharply increases, while [Fe(II)]0 = 5.0 mg/L, reaches minimum 0.3 mg/L higher reactive species (ROS) production. Water parameters such as color, turbidity, aromaticity were also monitored. Aromaticity significantly decreases min, confirming ring cleavage. Color turbidity initially intensify intermediate formation but later decrease progresses. Optimal conditions (1 mol SMX: 10 H2O2: 0.05 Fe(II)) ensure efficient with minimal depletion without excessive scavenging effects. These findings confirm process effectively removes improving quality, making it sustainable alternative for pharmaceutical wastewater treatment.

Sonocatalysis Regulates Tumor Autophagy for Enhanced Immunotherapy

ACS Nano, Journal Year: 2024, Volume and Issue: 18(42), P. 28793 - 28809

Published: Oct. 8, 2024

Immunotherapy stands as a groundbreaking strategy for cancer treatment, due to its ability precisely and safely detect eradicate tumors. However, the efficacy of immunotherapy is often limited by tumor autophagy, natural defense mechanism that tumors exploit resist immune attacks. Herein, we introduce spatiotemporally controlled method modulate autophagy via sonocatalysis, aiming improve immunotherapeutic outcomes. Specifically, synthesized tumor-targeting nanocatalyst based on semiconductor heterojunction composed Barium Titanate (BTO), Black Phosphorus (BP) integrated with Hyaluronic Acid (HA), referred BTO/BP-HA. Compared traditional catalysts, structure enhances energy band bending rapid electron-hole separation under ultrasonic stimulation, splitting water generate H
