- 中文摘要: Optimized experimental procedures including time of extraction, extraction solvent in Soxhlet extraction technique were sought for detection of trace ethion residues in soil. The largest recoveries over 96% were achieved with a 1:1 mixture of methanol and acetone as extraction solvent for three hours. In comparing EI, CI, EI-CAD, and PCI-CAD modes of a four sector mass spectrometry for detection ethion, it was shown the best monitoring mode to be EI monitoring of the M/sup +/ of ethion, m /z 384, which fragments to give the m/z 231 product ion. The limit of detection obtained was 170pg/g in soil.
