Abstract
Seven sulfonamides added to feed samples were extracted with DMF and hydrolyzed to the amines with sulfuric acid. After alkalization, the extracts were analyzed by GLC, using a Carbowax 20M column. Recoveries averaged between 94 and 104%. The described method is rapid and requires a minimum of manipulations.Keywords
