Sulfonamide residues in sediment and sludge from wastewater treatment plants
 Chaloupková, Petra ; Lacina, Petr (referee) ; Vávrová, Milada (advisor)
The aim of the bachelor’s thesis was a method optimalization for extraction of sulfonamides from sediment and sewage sludge samples from wastewater treatment plants. This optimized method was used for analyzing sulfonamides in real soil and sewage sludge samples. Antibiotics are commonly used as a prevention and medicament for human and animals. Drugs and their residues enter to wastewater treatment plants within excrements and then they can be a part of sewage sludge or they can occur in treated water. It can also enter environment as a part of soils or sediments. Three extraction methods were chosen for optimizing; a pressurized solvent extraction, a microwave-assisted extraction and an ultrasonic extraction. Extracts were cleaned by solid phase extraction and analysed by liquid chromatography with diode array detector.
