摘要：

A rapid and sensitive method for the detection and quantitation of organophosphorus pesticides in rice has been developed. It uses extraction with methanol-modified supercritical carbon dioxide followed by quantitation by a gas chromatograph equipped with an atomic emission detector operating in the phosphorus and sulfur modes. Evaporative displacement of the collection solvent during the supercritical fluid extraction stage allows quantitation of the analyte down to 10 ng/g without any intermediate concentration steps. © 1993, Oxford University Press.
