摘要：
Methyl bromide liberated by modified Malone''s sweep codistillation method or acid reflux method was converted to N-methyl phthalimide with sodium hydroxide and phthalimide in N,N-dimethylformamide. This derivative was determined by a gas chromatograph equipped with an electron capture detector (ECD). Recoveries were 81-91% from wheat, hay, lettuce, tomato and carrot fortified at 0.125-0.05 ppm, with the detection limit of 0.0006-0.003 ppm.
