摘要：

An efficient and sensitive procedure for extraction and analysis of dalapon (2,2-dichloropropionic acid) in water was developed. Acidified and NaCl-saturated samples containing dalapon were extracted with diethyl ether. After partitioning the extract through bicarbonate and back to ether, the dalapon was converted to its methyl ester. Analysis was by electroncapture gas chromatography. Recoveries of dalapon from water averaged 96%. and the minimum level of detection was 0.1 ng. © 1969, American Chemical Society. All rights reserved.
