DETERMINATION OF CARBOFURAN AND ITS METABOLITE RESIDUES IN COTTON SEEDS AND SOIL BY GLASS CAPILLARY COLUMN GC TECHNIQUE
用毛细管色谱法和同位素技术研究呋喃丹及其有毒代谢物在棉籽和土壤中的残留

Glass capillary column coated with OV-101 was used to analyse carbofuran and 3-hydroxy carbofuran residues in cotton seeds and soil. The technique depressed the thermal decomposition and the absorption of the pesticides during the separation and could separate the components of interest from the interfering substances. The average recoveries of carbofuran and 3-hydroxy carbofuran in cotton seeds and soil using the technique were around 80 percent and the primary loss of the pesticides during the analysis was contributed to acid hydrolysis and absorption, according to the results of experiments using 14C labeled pesticides.
