BIO PHOTOCATALYSIS OF METRONIDAZOLE, TRIMETHOPRIM, SULPHAMETHOXAZOLE USING NANOPARTICLES
Abstract
The presence of pharmaceutical residues in water bodies has become a growing environmental concern due to their persistence and potential health risks. This study focuses on the biophotocatalytic degradation of three commonly used antibiotics—metronidazole, trimethoprim, and sulphamethoxazole—using nanoparticles. The experiment involved exposing aqueous solutions of the drugs to nanoparticle catalysts under light irradiation. The degradation efficiency was monitored over time using standard analytical techniques. Results indicated significant reduction in the concentration of the pharmaceuticals, with degradation efficiency influenced by factors such as catalyst concentration, light intensity, and exposure time. The study demonstrates that biophotocatalysis using nanoparticles is an effective and eco-friendly method for removing pharmaceutical contaminants from water systems.
