Mobility of sulfonamide antibiotic sulfapyridine in different types of soil

Popis výsledku v původním jazyce

This contribution focuses on monitoring the mobility of sulfapyridine in different soil types. The main difference in the used types of soil was the content of soil organic matter. Simple sorption and desorption experiments in buffer solutions with different pH values were made. Adsorbed and desorbed amount of sulfapyridine was measured using UV-VIS and liquid chromatography. The water solution of sulfapyridine was used for experiments in real conditions when a plastic tube was put into the soil and watered with an aqueous antibiotic solution. For the following days, tubes were taken out of soils, separated and adsorbed amount was measured with UV-VIS. In addition, computed tomography was used to make models for molecular diffusivity. From these measurements, the diffusion coefficient was determined along with adsorbed and desorbed amount of sulfapyridine in different types of soils and in different values of pH. It was confirmed that the pH value and type of soil has an influence on the sorption of used antibiotic.
