Research progresson photocatalytic removal of sulfonamide pollutants from wastewater
Sulfonamide antibiotics have been used for the longest time in the treatment of bacterial and protozoan infections and are considered to be the first systemic antibiotics.These sulfonamide antibiotics have poor biodegradability,leading to bacterial bioaccumulation,biomagnification,and increased antibiotic resistance in various ecosystems such as the ocean.The photocatalytic technology using sunlight(or other light sources)to remove organic pollutants and harmful bacteria has always been considered one of the most valuable technologies in water treatment.Due to its advantages of simple operation,no introduction of secondary pollution,and clean energy,it has enormous application potential in the field of environmental purification.In recent years,it has been widely studied in water and air purification.In photocatalysts,semiconductor heterojunctions,as Z-scheme and S-scheme heterojunctions,are most effective due to high charge carrier separation,better charge transfer,and excellent photo redox potential.This article reviews the efficient photocatalytic degradation and mineralization of various sulfonamide antibiotics using hetero-junction photocatalysts,as well as the factors affecting the photocatalytic degradation of sulfonamide antibi-otics,including solution concentration catalyst dosage,pH value,etc.
