A simple, rapid, and efficient partitioning column consisting of acetonitrile on Florisil has been developed for the separation of pesticides from fish, beef and butterfat. The efficiency of the cleanup column is between 97 and 100%. 9 pesticides having partition coeff. between n-hexane and acetonitrile of less than or equal to 0.05 were satisfactorily separated from fat with good recoveries. When the column was used to clean up temephos in a fish extract, 99.91% of the fat was eluted with 20 ml n-hexane with no loss of the pesticide.
