Brooks, M.W. | Uden, P.C.
The insecticide abamectin is extracted from soil and animal tissue by supercritical fluid extraction. Supercritical carbon dioxide modified with 9% 2-methoxyethanol extracted abamectin from soil samples at levels up to 11 ng g-1 with greater than 80% efficiency. Recovery at fortification levels Of 5 ng g-1 were obtainable without the need for clean-up. Abamectin was also easily extracted from animal tissue at levels of 22 ng g-1 without interfering coextractives. Extracted abamectin was determined by liquid chromatography of a fluorescent derivative.
