title: Extraction of sulfamethazine from feed samples.
abstract: The efficiency of a number of published extraction solvents for sulfamethazine in feeds was evaluated. Poor recoveries were obtained with several of the solvents when sulfamethazine was extracted from commercially pelleted feed samples. Recoveries ranged from 48 to 94%. A 75% methanol acetic acid extractant gave the best results.
