Water pollution associated with antibiotic residues and colored organic pollutants leads to various potential risks human health the environment. This work develops an economical method that is suitable for removing both from water. The oxidation process based on a noble metal (Ag)-doped zinc oxide photocatalyst (Ag-ZnO) was selected as strategy investigation. Besides, tetracycline (A-Tc) methylene blue-colored (D-Mb) were target contaminants. With light assistance, Ag-ZnO showed significantly improved degradation efficiency A-Tc D-Mb at 90.6 97.3%, respectively. advantages of are also confirmed by faster rate constants, which more than twice fast those undoped sample. mineralization shows 93.5% 98.7% carbon removed solutions, result suggests being converted into inorganic substances. In addition, benefits using enhance safety, reduce negative effects environment, decrease treatment costs discussed.

This study evaluated an effective approach for the removal of chlorpyrifos (Chp) and atrazine (Atz) pesticides using graphitic carbon nitride photocatalyst (g-CN). Experimental results showed that under solar light, g-CN was able to remove 82.4% Chp 73.6% Atz at initial concentration 10 mg L-1. It also exhibited total organic efficiency 95.3% 84.7% after 150 min. Besides, is more with a degradation around 10% higher than visible light. The characterization confirmed high purity its strong UV light absorption ability, some extension into region. In addition, recent methods used were discussed evaluated. photocatalytic process most widely method removing compared other techniques. However, development suitable materials based on should be further explored enhance their
