摘要：
An analytical technique for analysis of dimethyl tetrachloroterephthalate herbicide and two degradates (monomethyl tetrachloroterephthalate and tetrachlorotere-phthalic acid) residues in turfgrass thatch and soil has been developed. It involves solid-phase extraction/purification and final gas-liquid chromatographic determination with electron capture detection. The degradates are determined as ethyl esters. The method is sensitive for dimethyl tetrachloroterephth-alate to 0.01 and 0.02 ppm for thatch and soil, 0.01 and 0.01 ppm for monomethyl tetrachloroterephthalate, and 0.02 and 0.01 ppm for tetrachloroterephthalic acid, for thatch and soil, respectively. © 1990 by Marcel Dekker, Inc.
