摘　　要：采用间断注射/连续光源火焰原子吸收法测定海水淡化多级闪蒸(MSF)排放水中铜、镍的含量,方法操作简便,水样过滤酸化后直接测定。结果显示,该方法无光谱干扰,采用基体匹配法后可以消除物理干扰,标准曲线线性良好,铜和镍的加标回收率分别为96%和106%,测试精密度分别为0.8%和2.1%。铜和镍测试的检出限分别为0.027 mg/L和0.024 mg/L,最低检测浓度分别为0.084 mg/L和0.058 mg/L。CS-FAAS combined with intermittent injection was used to determine copper and nickel in discharged water from MSF. This method was easy to operate, the sample could be directly determined after being filtrated and acidated. The resuh showed no spectral interference, no physical interference af- ter matrix matching and good linear standard curve. The recoveries, RSD, LOD and LOQ of copper and nickel were 96% and 106% , 0.8% and 2.1% , 0. 027 mg/L and 0.024 rag/L, 0. 084 mg/L and 0. 058 mg/L respectively.
