Under visible light irradiation, the effective degradation of a highly digested antibiotic known as metronidazole in aqueous solutions using Co/g-C_3N_4/Fe_4 nanocomposite was achieved. The effectiveness of the synthesized photocatalyst as a result of the degradation of the studied antibiotic under visible light irradiation was investigated extensively. The results revealed that the highest degradation efficiency for MNZ was achieved under the following conditions: irradiation time of 60 minutes, pH = 8, MNZ concentration of 5 mg/L, and photocatalyst dosage of 0. 7 g/L. In addition, MNZ's depletion began with the pseudo-first-order kinetic model. The best rate constant value was found to be 0. 0102 min1 with the correlation coefficient of 0. 992. According to the results of the quenching tests, it was discovered that hydroxyl radicals were the most common species responsible for MNZ decay. The Co/g-C_3N_4/Fe_3O_4/Vis system demonstrated a good result in the treatment of wastewater and real water samples.

At 25°C, the kinetics behavior and equilibrium adsorption of diphenhydramine and metronidazole from aqueous solution were compared to a commercial activated carbon and a commercial activated carbon. The adsorption capacity of MIL101-OH and MIL101-OH/CS was 634 and 573 mg/g, respectively, as a result of the addition of OH functional group and chitosan polymer. MIL101-OH/CS' maximum adsorption capacity was 600 mg/g, twice the adsorption capacity of MIL101 and four times the commercial activated carbon's maximum adsorption capacity.

The oral cavity is a unique place where wound healing must occur in the presence of a high-contaminated oral fluid, often resulting in infections at the suture site. Metronidazole-Chlorhexidine, a common antimicrobial agent used to treat oral ulcers and gingival inflammation, has been used to treat oral ulcers and gingival inflammation, but there have been no studies on the use of the drug in oral incision healing. The study findings showed improved wound healing and reduced postoperative inflammation. In Group 1 of research, there was a statistically significant decrease in post-operative pain, but not in Group 2, but not in Group 2.
