Contributions to the ethyl acetate application in residue analysis

Summary Atrazine was extracted from two weathered soil samples with the proposed micro extraction method using ethyl acetate as the extracting agent. The results were compared with other extraction methods tested. The proposed micro method was equally effective as the micro on-line method using acetone for the extraction and more effective than the Soxhlet extraction using acetone and methanol. Therefore, the proposed micro ethyl acetate method can be used for routine analysis.
