The aim of diploma thesis was finding of the method for the determination of drug residua in sewage sludge from wastewater treatment plant. Selected sulfonamide and diaminopyrimidine antibiotics, which are used in human and veterinary medicine, were selected as target comopounds. They are discharged to the sewer systems together with the urine and faeces and enter the sewage treatment plant, where they are not completely removed. They can be found in treated waste water or in sewage sludge. They can enter to the environment, where they can induce negative effects on organisms in soil and water ecosystem. An optimized method was used for identification and determination of these antibiotics in real samples from the large-scale waste water treatment plant in Brno-Modřice and from the waste water treatment plant situated in the area of Veterinary and Pharmaceutical University Brno. Antibiotics were extracted from sewage sludge by ultrasonic and by pressure solvent extraction (PSE). Waste water and sewage sludge real samples were concentrated and cleaned by solid phase extraction (SPE). For determination these antibiotics high performance liquid chromatography with diode array detector (HPLC - DAD) was used.
