摘要：

Methods for extractions and analyses of samples of natural water and basal salt medium for bacterial growth containing traces of chlorpyrifos-methyl have been developed. Aqueous solutions were extracted by high-speed stirring after addition of a small volume of hexane in the sample. Extracts of lower concentration were concentrated by evaporation prior to analyses by flame photometric gas chromatography to yield a detection limit of 1 ppb. The extracts from all aqueous solutions were found to be relatively stable for 45 days. The efficiency of the extraction methods was near 100% for the water samples and near 95% for the basal salt medium samples under the experimental conditions described. © 1979, American Chemical Society.
