In this study, we successfully synthesized MoS2 nano sheets (MNS) using hydrothermal synthesis and employed them as catalysts to degrade tetracycline wastewater in catalytic wet air oxidation (CWAO) system. We used many modern analytical instruments to characterize the synthesized materials, and the characterization results revealed that catalysts displayed a 2D nano sheet morphology. The experimental results of the catalytic wet air oxidation demonstrated that the MoS2 nano sheets effectively facilitated the degradation of tetracycline wastewater. Under the reaction temperature of 130°C, the tetracycline degradation rate was achieved more than 96% after 90mins. Also, the degradation process was conformed to the apparent first-order kinetic equation and Arrhenius equation. In addition, the catalyst maintained excellent degradation performance after recycling usage. The catalytic mechanism studied through DFT (density functional theory) calculation illustrated that under the condition of thermal excitation (105-160°C), MoS2 nano sheet was excited enough electrons and holes to catalyze the degradation of tetracycline wastewater.

Bioremediation is an alternative approach for the removal of pesticides from wastewater, offering advantages such as costeffectiveness and environmental friendliness compared to other wastewater treatment methods. This study aimed to assess the removal capacity of two filamentous fungal strains for the commonly used pesticide Cyromazine (CYR) and to monitor the pesticide removal using electrochemical techniques. The fungal strains, Rhizopus arrhizus and Aspergillus versicolor were cultivated in a molasses medium with and without the CYR pesticide. The utilization of sugar refinery waste molasses proved valuable in terms of cost reduction and waste reuse. The optimal pH levels (3, 4, 5, 6, 7, and 8) and CYR concentrations (3, 5, 7, and 10 mg/L) for achieving maximum CYR removal were determined. The results indicated that the cultures of Rhizopus arrhizus and Aspergillus versicolor achieved maximum removal efficiencies of 81.51% and 87.86% for CYR, respectively. Notably, this is the first paper reporting the successful removal of CYR from aqueous solutions using living fungal strains, specifically A. versicolor (a wild strain isolated from Turkey) and R. arrhizus, while monitoring CYR levels via electrochemical methods. The findings presented in this study serve as valuable insights for the development of new electrochemical applications in in-situ bioremediation processes.
