This study aims at determining the Minimum Inhibitory Concentration with Escherichia coli ATCC 25922 and cytotoxicity to L929 cells (ATCC CCL-1) of the waste generated by doxycycline degradation by the Fenton process. This process has shown promise in this treatment thanks mainly to the fact that the waste did not show any relevant inhibitory effect on the test organism and no cytotoxicity to L-929 cells, thus demonstrating that the antibiotic properties were inactivated.

Traditional homogeneous Fenton systems face limitations, including a narrow pH range, potential secondary pollution, and poor repeatability. In this study, these bottlenecks in tetracycline wastewater treatment were addressed with using carbonized porous polyethyleneimine-grafted lignin microspheres (PLMs) supported Fe-loading catalysts (PLMs/Fe-C). An optimized PLMs/Fe-C catalyst under specific conditions (carbonization temperature: 350 °C, PLMs: Fe = 1:1, and alkali lignin: PEI = 1:4) was developed, which proved to be an efficient Fenton-like catalyst for tetracycline (TC) degradation.

Chronic diabetic wound poses a pressing global healthcare challenge, necessitating an approach to address issues such as pathogenic bacteria elimination, blood sugar regulation, and angiogenesis stimulation. Herein, we engineered a BiWO@CuO-GOx bio-heterojunction (BWCG bio-HJ) with exceptional cascade catalytic performance and impressive sonosensitivity to remodel the wound microenvironment and expedite the diabetic wound healing. Specifically, the Z-scheme junctions of BiWO@CuO significantly augmented carrier separation dynamics, leading to the highly efficient generation of reactive oxygen species (ROS) upon US irradiations.

The frequency and intensity of harmful cyanobacterial blooms have increased in the last decades, posing a risk to public health since conventional water treatments do not effectively remove extracellular cyanotoxins. Consequently, advanced technologies such as the Fenton process are required to ensure water safety. The cyanotoxin cylindrospermopsin (CYN) demands special attention, as it is abundant in the extracellular fraction and has a high toxicological potential.

The present work investigated the application of UVC combined with electrogenerated HO (UVC/e-HO) for BTA degradation using a Printex L6 carbon-based (PL6C) gas diffusion electrode (GDE). The studies were carried out by analyzing the influence of the current density, pH and initial BTA concentration in the contaminant degradation process. Under optimal conditions using 0.

Copper-azole based formulations have been widely used to protect wood timbers against fungal decay. While these treatments are efficient for wood protection, leaching of both copper and azoles into the environment has deleterious impact on soils and surface waters. No bioremediation process is currently available for disposable of these wood wastes.
