Investigation of possible degradation reactions of amoxicillin molecule

Abstract

Amoxicillin is used to treat infections caused by bacteria, including infections of the ears, lungs, sinus, skin and urinary tract. Antibiotics those taken by living beings are disposed of from living metabolism as unchanged or little transformed. Antibiotic traces disposed of can not be treated in conventional wastewater treatment plants and enter directly to the receiving environment. In receiving environments, low concentrations of antibiotic traces can cause microorganism resistance increase and high concentrations of antibiotic traces can cause toxic effects. Therefore wastewaters those includes antibiotic traces have to be treated. In this study is discussed theoretically possible reaction pathways of amoxicillin, which has a high toxic effects and is able to dissolve in the water. For this purpose, possible reactions was examined numerically using Gaussian 09 package software. DFT method was used in theoretical study.
