摘要
介绍了一种以正己烷萃取 ,用气相色谱 -卧管式微火焰原子吸收法测定环境样品中二乙基汞的方法。该法简单快速 ,灵敏度高。二乙基汞的检出限为 1 9× 10 - 1 1 g s ;r=0 9996 ;RSD =2 3%。回收率 :底泥 93 7～ 10 0 7% ;土样 92 8～ 10 2 6 % ;水样 83 6～ 91 5 %。
A method is proposed for the determination of diethylmercury in environmental samples by GC-AAS with horizontal pipe mini flame atomizer. The samples were extracted by n haxane. The method is simple, sensitive and rapid. The detection limit for diethylmercury is 1 9×10 -11 g/s, r=0 9996, RSD=2 3%. The recoveries are 93 7%～100 7% for sediment, 92 8%～102 6% for earth samples and 83 6%～91 5% for water samples.
