建立了DB－WAX毛细管柱气相色谱法测定城市污水中烷基汞的方法。在优化条件下，测定范围为0.10～1.00 mg／L，甲基汞和乙基汞的相关系数分别为R＝0.9998、0.9999。当水样取1 L时，甲基汞检出限为6.9 ng／L，乙基汞检出限为4.4 ng／L。通过基体加标回收，甲基汞和乙基汞的回收率均可控制在90％～105％之间，测定结果的RSD均＜1％。
建立瞭DB－WAX毛細管柱氣相色譜法測定城市汙水中烷基汞的方法。在優化條件下，測定範圍為0.10～1.00 mg／L，甲基汞和乙基汞的相關繫數分彆為R＝0.9998、0.9999。噹水樣取1 L時，甲基汞檢齣限為6.9 ng／L，乙基汞檢齣限為4.4 ng／L。通過基體加標迴收，甲基汞和乙基汞的迴收率均可控製在90％～105％之間，測定結果的RSD均＜1％。

A gas chromatography method using DB-WAX capillary column was established to determine the mercury alkyl mercuryalkylide in municipal sewage.On optimum condition , the measurement range was 0.10~1.00 mg/L, the correlation coefficient of methylmercury was 0.9998 , the correlation coefficient of ethylmercury was 0.9999.When 1 L water sample was taken , the detection limit of methylmercury was 6.9 ng/L, the detection limit of ethylmercury was 4.4 ng/L.Through the recovery of standard addition , the recovery rate of methylmercury and ethylmercury was in the ring of 90%~105%, the RSD was less than 1%.
