摘　　要：建立了一种利用AA3连续流动分析仪测定饮用水中亚硝酸盐的新方法。研究表明该方法在亚硝酸盐浓度为0-100 μg/L的范围内有良好的线性关系，方法的检出限为1.34 μg/L，回收率为97.95%-101.78%。该方法具有分析速度快、检出限低、准确度、精密度高等特点，适合饮用水中亚硝酸盐的测定。A new method was established for determination of nitrites in drinking water by AA3 continuous flow analyzer in this re- search. The study indicated that this method had a good linear relationship when the nitrite concentration was in the range of 0-100μg/L. Its method detection limit is 1.34μg/L and recovery rate is 97.95%-101.78%. This method has a fast analysis speed, low de- tection limit, and high accuracy. It can be applied to the determination of nitritesin drinking water.
