| 摘 要： | 间接原子吸收光谱法测定水中的ＮＯ_３~－是基于银离子－１．１０－邻二氮菲－ＮＯ_３~－形成不溶性的络合物，剩余的银由原子吸收光谱法测定，从而计算出ＮＯ_３~－含量。本法简单，方便，快速，精密度令人满意。

| Abstract: | In this paper, indirect determination of nitrate by AAS has been studied,it is based on the silver ion-1,10-phenanthroline-nitrate formed in toa not dissoluble complex.Residual silver was determinated and the content of nitrate was computed. The method was simple, convenient and fast,and the precision of the method was satisfactory. |
