Abstract
An analytical method was developed to determine residues of haloxyfop-R and its methyl ester in soils and soybeans using gas-liquid chromatography (GLC) with electron capture detector (ECD). Soil or soybean sample was acidified and extracted with acetone. The extract was then subjected to ion-associated partition to individually separate haloxyfop-R and the neutral methyl ester. One phase containing haloxyfop-R was methylated with
기체크로마토그래피를 이용하여 토양과 대두시료중 haloxyfop-R 및 haloxyfop-R-methyl의 잔류 분석법을 개발하였다. 토양 및 콩시료를 산성화한 후 acetone으로 추출, 두 화합물을 동시에 추출하였으며 pH조절 분배법을 이용하여 각 화합물별로 분획화하였다. Haloxyfop-R 분획은
